From Kill Everyone? I don't know how to calculate the factor itself, just that it is derived somehow from ICM. I know how to use the factor they give in their tables in calculations:
Express the chip pot odds in a
x:1 ratio, then divide
x by the bubble factor.
So if I am getting 3:1 on a call, and the bubble factor is 1.5, 3/1.5 = 2. I should use 2:1 as my "real" pot odds, because of the value of survival in a tournament.
As a practical matter, I'm not doing that at the table, and ICM tools incorporate it into their results off the table . . . What works best for me is reviewing examples.
