How come on Pokerstars they take the rake out on every turn? Shouldn't the amount they take out be considered part of the pot for betting?

I guess since nobody can win the rake, its not considered part of the pot.

But it would make for a slightly larger game if they left in the rake untill the end.

Which, interestingly enough, would make for slightly larger rake over time.

PS is the only site I know of that holds the rake outside of the pot calculations. On UB for example, the rake is animated beside the dealer tray, but still included on the bet sizing slider.
