This is a really difficult question to answer.
In fact, the question is not so difficult from the point of view of mathematics
Knowing your win rate and std.dev over a long playing distance (from the tracker), you can absolutely determine what bankroll is required in order to have a certain risk of ruin, which everyone chooses for himself. For example, it is good to choose the risk of ruin R=5%, otherwise it will be an overly conservative game. But if poker is your profession, then it is better to choose the risk of ruin no more than 1%-2%
The formula that is used in the primedope calculator is completely accurate and works for any type of game:
BR = {D/2m}*Ln(1/R)
D - dispersion
m - win rate
R - risk of ruin
D=[std.dev]^2
If R is chosen equal to 2%, then Ln(1/R)=Ln(1/0.02)=Ln(50)=3.912
For example, your indicators in the tracker are: m=7BB/100, std.dev=90BB/100
Then BR= {(90^2)/(2*7)}*3.912=2263.4BB or about 23 stacks of 100BB each. It is with this BRM for a player with a win rate of 7BB/100 and std.dev = 90BB/100, the risk of ruin will be equal to 2%
And if we consider a player with indicators m=2BB/100, std.dev=100BB/100, then in order for him to have a ruin risk of no more than 2%, a much larger bankroll will be required:
BR= {(100^2)/(2*2)}*3.912=9780bb or almost 100 full stacks of 100bb each.
