pointing out flaws in the model is kind of moot because

1. you can't quantify how much if any error it induces
2. you dont have a better alternative.

typically models are meant as a high level guide.

specific extreme situations will have error.

the answer here isn't even close.

to think any player has a 75/25 edge over a table full of people is pretty ridiculous unless there are player at the table that will routinely call all ins with nothing.
