i said that just to mean in a cash game PFRs aren't necessarily influenced by the blinds as much as they are by the average stack size and amount needed to limit the field post flop.
In a 1/2 Online game 8 dollars is standard
In a 1/2 Live Game 15 and up is common
At some tables however you need to increase your raises bc 15 dollars will not limit the field, in other games you can decrease your raises bc 10 will do just fine.
A 5/5 Game where 700 is the average stack is going to play lower than the same 5/5 Game where 1200 is the average stack
With that said, I agree, take it out of the sig.
