Well Vince,
I'd say that what you are essentially saying is "doing the math on the fly is not important as long as your strategy has the math embedded in it".

I'd tend to agree. Often if you look at a reccomended play an author makes, and then go do the math, then it makes sense.

So I suspect it is possible to not have to be a mathematician who can calculate 5 decimals in your head on the fly. Your strategy just need to be underlying mathematically correct.

Clearly math underpins the whole game, if not the whole universe. But whether you have to be running a calculator in your head constantly is a different question.
