Happy 10th Birthday Sportpunter

Sportpunter is celebrating its 10th year in business. That’s 10 years of giving out predictions from its website. From the humble start of giving tennis predictions and cricket matchups from the Swinburne University website till now, it’s been a great experience. Many of our followers have followed us from the very beginning and continue to do so now, so thankyou to you guys. Without your support, Sportpunter would not be operating.

Who remembers the first days of Sportpunter which launched in November 2002? The simple, self made graphics I once thought were pretty special as shown here:

http://web.archive.org/web/20021201005600/http://www.sportpunter.com/

The fact that the picture would change simply by putting your mouse over it! Tennis was of course the sport that gathered the most attention at first. The profits were great early, and I didn’t even include qualifying and challengers in the model. Goes to show how advanced bookmaking has come since the early days.

Formula1 predictions were also produced every week, but this was merely a way to get free grandstand tickets and a bit of publicity for Swinburne! Cricket, AFL, NRL, Rugby Union and English Premier League soon followed, with AFL showing the biggest profits of them all (and continues to do so now).

The business kept going so smoothly and increasing in numbers that I had to stop my PHD to give enough time to it. After 10 years at University studying statistics, mathematics and psychology, it was time to head out into the real world and get a real world job.

However, not many people believe today that I still have a real world job. With flexible hours (despite having to work every day – 365 days of the year), it sure is different than your standard 9 to 5 getup. But full time work meant more sports analysis, a forum, special articles about sports gambling and a new designed website as shown here: http://web.archive.org/web/20040624032849/http://sportpunter.com/

In the past 3-4 years we have seen a massive increase in the number of sports, with Ice Hockey (EU and NHL), Basketball (NBA, NBL, Euro, NCAAB), NFL, Soccer, Golf and Baseball being added to the Sportpunter sports list. Another new designed website, more in depth statistical analysis, and we are where we are today.

Ten years ago I was guaranteed a job giving tennis predictions at another website for a split profit deal, but whilst travelling around Australia, was told that the position was filled by someone else. Little did they know. That other website now doesn’t exist, but Sportpunter continues to go ahead strongly.

Ten years is a long time. It is especially a long time to be constantly giving out gambling predictions. This just shows the long term record and long term success that we have had with our betting. If our predictions had been non profitable, or our records dodgy we would have been out of business long ago. But Sportpunter continues to thrive, and will hopefully do so into the future for the next 10 years.

I’m giving myself a pat on the back for the 10 year anniversary of Sportpunter, and if you had been following Sportpunter in the past, then I’m sure you would as well.

Thanks to Steve for the webpage design and constantly correcting my spelling errorrs. 😉

And Thanks for everyone’s support, and here’s to the next 10 years ahead.

It’s all about the Basketball

College Basketball Season Commences

The American College Basketball season has just commenced, and once again we are giving away predictions free of charge. Predictions are updated twice daily to make sure that all the predictions are released when the odds are available. With a large number of matches played per year, this sport is great for getting a lot of turnover on.

Totals betting is the way to go here, and we have a betting history record going back to 2003/04. Overall we’ve made 6.6% ROI from 7300 bets. The past 3-4 years we have made in between 2% and 5.6% ROI per year, with the last two years recording nearly 1250 bets. Suggested bets and full betting histories found here: http://www.sportpunter.com/sports/basketball/college/

NBA Early Profits

We told you how the Sportpunter model makes massive profits early in the season, and we were correct once again in 2012/13. Already this year from 68 bets we have made 20.8% ROI and $3,800 profit. Totals as well have been on fire, with 71 bets made at a 59% success winning rate. A return on investment of 15.6% per bet has been made. Amazing results. The predictions are free, so make sure you get on now, early in the season, whilst the going is good. Full details here: http://www.sportpunter.com/sports/basketball/nba/

Euro Basketball

It really is all about basketball this week, and Euro Basketball betting has not been struggling at all. From over 1500 bets since November last year, Euro Basketball betting has made 1.7% ROI betting head to head, 5.0% ROI betting on the line, and 4.5% ROI betting the totals. That’s a very large sample size, with big profits. Like NBA and college basketball, Euro Basketball is also free of charge on Sportpunter. So get on board with all the details here and start winning: http://www.sportpunter.com/sports/basketball/euro/

Australian (NBL) Basketball

The Australian Basketball season has started as well, and profits are great to start off with. Whilst only a limited number of bets have been made, profits have been nice. 17 bets at 8.5% ROI for head to head betting and 18 bets at 9.9% ROI for line betting. Totals unfortunately have shown a loss from their 17 bets, but it’s very early on in the season and hopefully, like previous years, profits will continue. Check out the 7 year betting history and predictions here for NBL: http://www.sportpunter.com/sports/basketball/nbl/

NBA Model for season 2012/13

The NBA season is set to start in just one day, and once again Sportpunter will be giving away predictions for free of charge. We’ve been running the model for 2 years now and have had some fantastic success. Last season we made 5% ROI betting the lines and 2.5% ROI betting the totals, with similar results the previous years.

What’s more, is that the model seems to do better earlier on in the season. Line or handicap betting, made 5% ROI in the first 6 weeks of the 2010/11 season, and an incredible 25% ROI of the first 6 weeks of the 2011/12 season. This from about 350 bets.

Totals betting also fared well at the start of the season. In 2010/11, we made 9.6% ROI from 474 bets for the first 14 weeks, whilst in 2011/12, the first 14 weeks netted 5.4% ROI from 345 bets. Full betting history results are shown here.

Clearly, the model has been very profitable, and especially earlier on in the season. With only a day to go, make sure you check out the free Sportpunter NBA predictions as shown here: http://www.sportpunter.com/sports/basketball/nba/

NBL Season 2012/13 set to start this friday.

nbldragonsThe NBL (Australian basketball) starts this Friday, and for the 7th season in a row, Sportpunter will be providing predictions. No doubt it is one of our best models, and we also believe it is one of the weakest markets out there that we can exploit.

In 6 years that we have been providing suggested bets we have made over 11% ROI betting on the totals from over 500 bets as shown by the betting history here.  This includes an incredible 31.5% ROI profit last season. Head to head betting, hasn’t been quite as good, but a still very profitable 3.6% ROI has been made over the journey.

What is more pleasing, is that last year we decided to track handicap or line betting for the first year, and despite a small loss in h2h betting, a very nice 15% ROI was made betting the line. Seems to me this could be the way forward.

So with the season starting this weekend, and the short pre season already over, one should be getting on board as soon as possible. Click here for all the subscription options

NFL Season 2012 underway: betting by round

The NFL season for 2012 has started round 1, with the first gameof round 2 set to start on Thursday  between the Bears and the Packers

Once again Sportpunter will be offering our predictions for every game, and if previous years records are to go by, we should have another profitable year. Full results are shown here for our model: http://www.sportpunter.com/result-history/nfl/ and these show that we recorded a 10% ROI profit betting the line and a 3.3% ROI profit betting the totals. In total over the two years we are up 5.5% ROI betting the line and 4.7% ROI betting the totals  from about 400 bets each respectively.

But interesting is how the model goes throughout the year. Whilst we only have a small sample size of two years, it might be interesting to see how the profits come in round by round. Shown below is the breakup of betting and profits for line and totals betting per round, followed by a brief summary.

Totals by round:

203$716.42-$75.92-11%
212$574.25$207.0436%

 

Clearly it shows that totals betting seems to go well from the word go, round 1, and if anything swindles a little later in the season. The opposite is true of line betting. Despite some big wins in round 3, it has taken until about mid-way through the season to show nice profits. Of course as I said, this is only a very small sample size, and one shouldn’t look into it as gospel, but there is good reason why the model might struggle a little early on with player movements between teams.

Either way, hopefully we get around the same type of success that we have had as previous years for what is one of the most popular bet sports in the world.

Soccer predictions are back online

Yes the most popular sport in the world is once again being modelled by Sportpunter after some technical issues. Every game from over 100 different divisions have been analysed and predictions will be out every day at around 5pm AEST.

Predictions will and do include head to head bets, line bets and totals bets, the latter of which has been reworked of late. A betting history has been provided and is also updated every day, and we hope to get betting histories out for each individual league in the short future as well.

But for all you soccer buffs. Soccer predictions are back! Link here: http://www.sportpunter.com/sports/soccer/

Sportpunter models Staking System

We previously looked at how well Sportpunter models had gone in the first half of this year. The results were very good indeed with the average bank increase of about 250% to 400% of your starting bank depending on your strategy. Now, we will look at the strategies and determine which is the best one – well at least discuss it with a little bit of data.

The following graph is how one would have gone betting a moving bank (after every week), different moving banks for each sport, and a constant bank for 1/15th Kelly divisor. Considering that all methods are betting on the same bets, they all generally follow each other.

 

 

The moving bank scenario finished with the highest profit for the first six months for 2012 despite a lot more variability over that time. When things were going good, and you could put a few good weeks in a row together, this is when the moving bank strategy excelled. However, the contrary is also true. Given a losing streak, the moving bank suffered more so that the constant bank.  This is true also to some degree for the moving different banks, though hardly as extreme.

Of course how much profit one made during a certain amount of time is very dependent for the moving bank scenario on the last few weeks, whilst with a constant bank, as the name suggests, each week is consistently as important in the final profit amount.  However more interestingly is the graph below which shows the finished banks (from $10,000) for each of the three methods.

 

 

Clearly the above graph shows that the constant (and moving different bank method) are preferable in the first half of 2012 if the Kelly Divisor is less than about 12. For larger more conservative divisors, a moving bank is preferable.

Now naturally, the above analysis implies that you use the same Kelly Divisor on all the sports. One might decide against this as they are more confident on certain sports and sports models than others. But despite this, the point has been proven to some degree, that a constant bank is preferable for smaller and more risky Kelly Divisors, whilst a moving bank is more preferable for more conservative Kelly divisors.

This to me, makes logical sense. But what is the best Kelly divisors and strategies for all the sports? Well soon we shall be providing an excel spreadsheet for you to play around with, but next up we will be looking at the Sportpunter model’s record going back several years.

Sportpunter profits 1/1/12 to 30/6/12

There’s been quite a lot of talk in the forum and elsewhere about how best to manage your money. Should you use a moving bank? Adjustable after every day, or every week or month? Or maybe just adjust at the end of the season.

Furthermore, this is a great opportunity to tell everyone how well, or bad, the Sportpunter models have gone in the first half of the year.

We’ve download all of the results from all our models in all our sports, and worked out how much we would have made this year, had we started the year with a $10,000 bank and betting every sport at various Kelly divisors. The sports that we have in the analysis is as follows:

 

 

  • AFL – Line betting
  • MLB – h2h
  • MLB – totals
  • NCAAB – totals
  • NBA – line
  • NBA – totals
  • NBL – line
  • NBL – totals
  • Golf – h2h
  • NHL – totals
  • EU Ice – Line
  • EU Ice – Totals
  • EU Basketball – Line
  • EU Basketball – Totals
  • NFL – Line
  • NFL – Totals
  • NRL – h2h
  • Super15s – h2h
  • ATP – h2h
  • WTA – h2h

Now of course, should one use slightly different combinations of sports one would come up with different results, but the main sports to bet on in my opinion are above, even though some are relatively new. Keep in mind that not all of the above sports provided a profit in the first half of 2012. NHL totals, EU Basketball totals, NRL, Super15s and WTA all provided reasonable losses. Whilst NFL totals and NCAAB Totals provided small losses from small turnover.

Firstly, the results of the Sportpunter’s models can be better shown using constant Kelly. From a $10,000 bank, the results of how one would have gone betting all of Sportpunter’s above models at various Kelly divisors is shown below in the graph.

 

The graph above shows that the finishing bank should end up somewhere between $27,000 to $44,000 (divisors 20 and 10), at the end of six months. This means a one would have finished the first half of the year, almost tripling your bank up to more than quadrupling it. Very good results indeed.

Once again, it must be stated that it is dependent on what odds you receive and what sports you bet, but the true significance of how good the Sportpunter models is, is shown above.

As an example, shown below is how the year panned out for someone betting at 1/15th Kelly on all the sports.

In the next post, we will have a look at different Strategies, from Moving Banks, to separate banks for each sport, and will also give you the opportunity to download the Excel spreadsheet that gave the above (and next articles) data for you to play around with.

Hawthorn’s Bookmaker Line winning streak

With Hawthorn’s turn around since losing to Richmond 2 month ago, I thought why not write an article about the Mighty Hawks (as you can see I might be a little biased here!). For those following the AFL, you might be aware, that Hawthorn has dominated the last 7 weeks of football and last week capped it off with a brilliant display against Collingwood.

In fact, every week for the past 7 weeks, they have easily beat the bookmakers line, a feet which I thought was pretty impressive. But is this a record and how many times has this been done before?

Well I decided to check it out. Given that I have all the bookmakers lines in my database going back to 2005, I will check out what the record is for the most number of matches in a row that a team beats the line. The results are below:

Year Round Team WinLinesStreak
2007 20 Geelong 15
2005 23 Sydney 9
2006 10 Collingwood 9
2006 22 Fremantle 9
2009 10 Melbourne 7
2009 15 Collingwood 7
2011 6 Collingwood 7
2011 8 Geelong 7
2012 17 Hawthorn 7*

 

Turns out that Geelong have the record, and quite comfortably. 15 matches in a row they beat the record, before losing to Port Adelaide by 5 points at home, when the line was -25.5. For those historians of the game, you might remember that Geelong went on that year to win the premiership, this time defeating Port Adelaide  by a whopping 119 points.

Second on the list is Sydney, Collingwood and Fremantle in the years 2005 and 2006. That year, Sydney also won the grand final, whilst in 2006 Fremantle made it to the prelim, and Collingwood, despite starting the season well, faded in the second half and eventually lost the semi-final.

There’s a whole group of teams with 7 wins in a row. Collingwood make the list twice in 2009 and 2011, whilst Hawthorn as mentioned in there with 7 in a row which they might extend this weekend.

But the most interesting one there with 7 bookmaker line beats in a row is Melbourne in 2009. Because despite winning 7 line beats in a row, Melbourne at Round 10 were on the bottom of the ladder with only one victory to their name. Turns out that their losses were not by much, and they were struggling in some cases to win the match, despite getting across the line.

So can the hawks extend their bookmaker line winning streak? Hopefully, but it will take a mammoth ask to break Geelong’s record of 15 straight line betting wins in a row.

 

UPDATE

A quick update, showing the average winning margin over the line for the teams with the longest streak. As expected, Melbourne have the smallest with only 15 points on average defeating the line. This isn’t surprising as they lost almost all those matches. Hawthorn’s recent winning streak of 7 on the trot has seen then have the highest average winning margin by some margin. Although, should they be lucky enough to get up to Geelong’s streak of 15 in row, one honestly would say it would be hard to keep up with that degree of victories.

Year Round Team WinLines Av. Win Margin
2007 20 Geelong 15 31.3
2006 10 Collingwood 9 35.4
2006 22 Fremantle 9 31.3
2005 23 Sydney 9 27.7
2012 17 Hawthorn 7* 42.1
2009 15 Collingwood 7 28.4
2011 6 Collingwood 7 24.5
2011 8 Geelong 7 19.1
2009 10 Melbourne 7 15.1

Analysis of 2011/2012 NBA Season model

With the 2011/12 NBA season now complete and Miami Heat getting up to win, it’s probably time that we check out the Sportpunter NBA model and see how we went in this cut short season.

Results are good for the 2011/12 season, which backed up the record of the season prior. Line betting saw 522 bets made for a very healthy 4.8% return on investment. This is up from the borderline 0.7% ROI made the year before. A total of 1143 bets now have been made for 3.6% ROI as shown here.

Totals betting had 511 bets with a nice 2.5% ROI profit. Lower than the previous years of 5.4% ROI, but still good. Over 1000 bets in total at 4.7% ROI over two seasons is very pleasing indeed.

Head to head betting had some technical problems with odds not being readily available all the time. Hence only 165 bets were recorded at 2.4% ROI, but still in the 2 years we have had 621 bets at 3.4% ROI.

Either way, all h2h, totals and lines have made profit in each category and in each year, which is very pleasing indeed.

We should previously, that the model does especially good earlier in the season, and with this season starting late, it was hard to say how we would have gone. However results show that stopping betting after week 9 for h2h, week 7 for line betting and week 14 for totals provided the most profit. Quitting looking at the model at these times would have provided 26% ROI betting h2h, 22% ROI betting on the line and 5.4% ROI (with more bets) betting the totals.

Of course it is easy to say in hindsight when to stop betting the models predictions, but what is clear is that the advantage for the model is early on in the season.

Shown below is a short analysis of the 2011/12 season for NBA for totals betting. I shall summarise them here.

Firstly it looks as though the whole season went well, expect for the months of May and June. It seems like the model might not perform that well during the playoffs. There were lots of over bets during this time, and just like Ice Hockey and other American sports, it appears that lower scores could well appear during the playoffs (hence why more overs bets).

Interestingly overs lost 1% ROI overall, whilst unders betting made a staggering 15.9% ROI from 124 bets. As previously noted, we suggested a minimum 17.5% overlay betting the totals, and the same trend occurred again in 2011/12. Had we just bet totals at 17.5% overlay or greater, then we would have made 254 bets for a very handy 5.8% ROI. Not bad at all. If you had of averaged $1,000 a bet, then you would have profited over $14,000 for the year.

If you had stayed away from the playoffs as we previously suggested, then the profits would have been bigger. You would have made 226 bets for a very handy 7.3% ROI. Very nice. An average $1,000 bet would have netter you a season profit of $16,500. And that’s only totals betting.

So signs are good, and the model has performed well, and also has been consistent year to year in the two years operating. Hopefully this trend will continue.
