That was written before learning that your model has a particularly high Trifecta strike rate and did not depend on larger collects as I first assumed.

If as it seems you can make 30% Trifecta POT betting all 16,000 races a year it makes your model beyond anything I have contemplated.

So the big question is why haven't you actually dipped your toes in the water?

You don't have to try it with the presumed $20 bet required for financial independence. If you started with just 50 cents you wouldn't do too much damage but it would give you a feel for whether you've miscalculated somehow.
