Under-over researching results after 66 games

What is going on with my research about betting on under or over in Basketball? Nothing so special, I would say, and the reason for that is the fact that the ROI has dropped from 17% to just four percents. However, there is good news and this is Gauss method for least square approximation. This is the most profitable method. Yes, with just four percents ROI, but it is a start. May be the way that the data is being collected is wrong, or maybe 4% is not so small profit. We will see.

Here are the results:

Under-over percentages from previous matches give 95.5 ROI
Under-over percentages from previous special matches give 101.3 ROI
Gauss method with data collected from last 10 matches for every team give 104 ROI
Gauss method with data collected from last 10 mutual games give 98.39 ROI
Average score made by teams in last 10 games for every team give 101.29 ROI
Average score made by teams in last 10 mutual games give 89.71 ROI

The last row is really a surprise for me. How is it possible the average for mutual games to be the worst result? Really strange, but a fact.


17% profit so far in my basketball under-over research

I cannot say I am satisfied with the results from this research. I definitely expected more from Gauss less square approximate method. I see that there is profit, but I expected more. Even so, 17% pure profit from 31 matches with betting on under over in basketball is not bad.
Here are the stats.

% L + %i L + G L + Gm L + Avg. L + Avg.m L +
61.3 54.8 41.9 58 45.1 38.7

If we start talking in profit percentage, best results shows my old method of betting, where you betting under or over depends from all previous matches for both teams. The profit there is 17%. However, as I learned from previous NBA regular season this method is going to be less profitable at the end of the season, because bookies start to level under

Result on my research after 18 games in WNBA

Last week my betting study was occupied only with the research in basketball under or over ending. I wrote a few times about it and I will do it now, again. It is time for evaluation after the first 18 matches already played.

I won’t be explaing again which methods I use. You can read more about them here.

There is 16.1% profit in two of the profits. The other four are below the line after those 18 games. However, as we all know we have to wait for the final matches for making analysis.

Here is the table with the result after 18 games in percentages:

% L +
%i L +
G L +
Gm L +
Avg. L +
Avg.m L +

One mark here. All odds here are 1.91


Results from my basketball betting research

It is a bit strange for me but my basketball under over research shows similar results. I use 6 methods for picking matches and all of them give results around 50%. This of course is 100% unsatisfying, but my research will continue.

Here are the results after 9 matches on WNBA:

Research about basketball under – over betting

I am starting a quick research on a few different strategies about betting on under or over at basketball games. I will use WNBA because it is only one major championship where matches are on right now. Few words about those different strategies: the first one I have used before in NBA last regular season. I follow the under

Bet under on Phoenix matches in WNBA

I am going to bet under on next five Phoenix games with martingale. I know it is a bit dangerous and I can lose all my bank, but I’ve got some reasons. From the beginning of WNBA Phoenix played 8 matches and all of them are over.

The longest strike of over I know about was New York’s last season with 12 overs in a row.

I think Phoenix will make at least one under in the next few games. So, crossing fingers.


Under – over profit in Spanish handball league

Few weeks ago I started to search for continuation of my simple NBA betting system. I found out something that most of you already know

A quiz for punters

nba chart for under and over

nba chart for under and over

  • Can you make money from this chart above? It is for under over betting in the whole regular season in NBA. The yellow line represents over endings, the pink one is for under rating and the blue one is the percent between them. I must say here that the chart is divided by periods of 60 matches in NBA and the yellow and pink lines are the matches multiplied twice
  • Finally, there is profit with streaks in NBA

    Finally I found some profit in under over streaks in NBA. The trick is to bet on every 5th game in the row and to place only one bet. Not more, only one bet. However, the ROI is so small, that it is not worth to play it at all. If, I have to talk with numbers the ROI is exactly 105.82%.

    Not so good for the entire regular season.

    So, I have to say it. I am really disappointed. I have read so many times the streaks are the best way of betting. Things like a punter will always has profit if the bet is placed on the 4th match in the row etc, but all of this is simply not correct for under
