The analysis is based on the histogram of the 800 bets I manually counted.
I found that the odds between 1.2-1.6 and 2.2-2.6 are loss-making, while between 1.6-2.2 and 2.6-4.0 are profit-making or non-loss-making. Of course, my data volume is somewhat small and not necessarily convincing. It would be better if you could add your own statistical functions to the report.
Although I have a small amount of data, I still find that the lower limit of odds should not be too low. It should be set at more than 1.5, thinking that the odds of 1.2-1.6 need several successive wins to offset the loss of a failure.
