Hello! So I have been struggling how to calculate ratio of bluff combos in turn jam pots.

I know that with zero equity and with potsize bet i should be bluffing around 33% to make a villans call indifferent. But how on earth i can correctly calculate how many bluff combos i should add to that. To demonstrate my question here is imaginary example:

I raise pre, cb flop, and now on the turn I have 100 combos in my value range and infinite number of one card straight draws.

If my blufs have around 25% eqiuty on pot how many bluff combos should i jam?

with zero equity i should bet about 50 combos, but when I am risking only 25% of my bet (i bet pot (100), villan calls pot: total pot 300. i have 25% equity on pot= 75, so I am effectively risking 25 chips instead of 100) how that affects to math behind this compared to spot where i would have 0% pot equity.

hopefully atleast someone could understand my question and i realy would apriciate if anyone would like to share their thoughts about this issue!
