I am not interested about my play. I would make that push anytime with any 2 cards, because blinds are regs. Thing which is important here is BB calling range. So, i already made following calculations:

BB odds: 1.51:1
Share of pool if he folds: 10.58%
Share of pool if he wins: 25.89%
Equity vs random hand: 64.9%

and have following questions:
1, How to calculate rest part of math? Is it correct(Equity*pool if he wins)? Guess not, i have never done that kind of math before
2, What would be the right way to calculate Share of prize pool? I made it this way
Chance to finish top 5 / 10 + %of chips in play you have / 2.
Simplified version would be "ICM spreadsheet for don for half of share + current chip stack in $".
But i`m concerned i`m wrong. In that way of calculation i must assume that he will ALWAYS get his part for chips he has. Multiplying instead of summing would make more sense for me, because chance to finish top 5 also means you get money for your stack. Anyway, you get a random number this way.
3, What should be BB calling range in this spot?

I hope you guys wont leave me alone here, i need help
