[formula_2002]

Maintaining one’s level of significance over a growing number of races, will cause a lowing of win% and % profit.
The attached excel file indicates that if one maintained a significance level of 2 standard units, in a game that offered 1-1 odds, after 10 plays the player could be ahead by a 63% profit . After 100 plays the profit is lowered to 20%, after 1000 plays the profit is 6%

The file also indicates that if someone withheld 15 cents on the payoff for each dollar, one must continue to increase the level of significance over the growing number of races, just to break even.

The chart covers 1-1 odds, 3-1 odds and 10-1 odds.

It’s also interesting to note, that as the odds increase, in that game where 15 cents is withheld for each dollar, the initial plays require less significance.(column R).
Corrections will be welcome.

But this isn't really how you'd measure performance. If you're maintaining your significance level, that means your win% is declining. There's no reason why it'd necessarily do that.

Increasing the significance level is pushing the area of the curve further and further into the tail (not an easy task).
It looks like the chart is saying that the more races you play, you must increase the significance to maintain the win % (which one, 82%, 60%,53%...).

I kinda look at it the other way around... as you maintain your win%, the significance level is increasing the more races you play. I think we're just talking about whether the tail is wagging the dog, or vice versa.
