Adjustment of Calling Ranges

[whyherro]

Situation: Small stakes sngo is down to the last 5 or 6 people and you are on the button with 10BBs. You check SNGPT to see if you should push your hand or not, it reads push - so you do. No callers.

In the cutoff the same sequence arises, it folds around to you and you have a pushable hand. If we assume villains calling range for a push on the first hand was top 20% of hands, how might we expect this to change for the second push?

What if we push and get no callers, and push again from the hijack? Are villains calling with 20% again? 25? 30?

2+2, what is your feel for how people adjust their calling ranges for every subsequent push? Is it linearly related to push frequency? How many pushes (or with what frequency) does (or should) it take someone to adjust their calling range?
