What about calling a hand? Why cannot I not to do that? Math please, if you can

What if the players are going to call an all-in push about the same as a 2.5 blind raise, and you're at 10-13 blinds.

What if you know that a player will either fold to your 2.5 blind raise, or push if he has a decent hand, as in you have this read on him? The other night I realised this player was pushing good hands in this situation, and folded most other times. Saved me from busting when he pushed me all in with his AQ, the only time he did push after about 6 steals. He called once, but an all in continuation bet scared him off; this continuation bet would work approximately 2/3s of the time, since they only hit that often on the flop, with exceptions to pockets or particuarly high cards/draws. So, if they did call I would still steal most of the time, with more in the pot.

Unless you can prove otherwise, it seems that push-fold mode is more for when up against players who actually know what they are doing....
