Recommended bankroll for <5% bust risk, given your current parameters:
PLO standard deviation is typically 100-150 bb/100 compared to 60-80 bb/100 for No-Limit Hold'em. This means PLO players experience swings roughly 1.5-2x larger than Hold'em players at the same stake level. The four-card starting hand structure creates more multi-way pots, larger pots, and more complex equity distributions.
A winning PLO player can have 50,000+ hand downswings. This is not a sign of playing badly -- it is the mathematical reality of high-variance poker. Even a strong 5 bb/100 winner will experience stretches of 20,000-50,000 hands below their starting bankroll. Running below EV for months is completely normal in PLO.
Bankroll management is the #1 skill for long-term PLO success. Because variance is so much higher, PLO players need significantly larger bankrolls than Hold'em players. A conservative approach is 30-50 buy-ins for the stake you are playing. Moving up too fast or playing with too short a roll is the most common reason winning players go broke.
Each colored line represents one possible future. The dashed white line is your expected value (EV) -- where you would be with zero variance. The shaded bands show 1 and 2 standard deviation ranges. About 68% of outcomes fall within the inner band and 95% within the outer band. The red dashed line marks your bust threshold. Run multiple simulations to build intuition for what realistic PLO results look like.
