When practicing with GTO, I hope that my buy-in will not be zeroed out every time, but can continue to accumulate, so that I can see whether I am making a profit or a loss when practicing with GTO.


The issue is that GTO strategy changes with your stack depth, so this just couldn’t work in practice mode, which only lets you replay a single structure repeatedly.
And just to clarify: you’ll always be losing money against GTO regardless of how you play, which makes it feel a bit pointless from that perspective too.
