Well so much for being 99% sure
I uploaded version 0.8 fixing the stack 2 vs stack 6 typo and adding 0 as a default stack size. I can't check accuracy of calcs right now so let me know if it seems right.

And a quick lowdown on how the numbers are calculated with some made-up numbers:
Your current EV = E (ex. 15)
Increase in EV if win allin against opponent = W (ex. +5 to 20)
Decrease in EV if lose allin against opponent = L (ex -15 to 0)
Bubble factor = L/W = 3
Because of the non-linear value of chips your Bubble Factor can never be less than 1.
