Hello
I have just started to use PIO to improve my understanding of the game and have trouble understanding mixed strategies which is usually the case with PIO outputs.
For example, I am in a 3-bet OOP SBvsBU as PFA with AA and flop is J78dd
Now, frequencies-wise

It seems PIO bets this hand very frequently on the flop but if we look at the EV of betting and checking

The EV's are super close.
Does this mean
* In a game where there is absolutely no need to balance, It doesn't matter at all whether we bet or check since the EV of both actions is the same and we should look for other exploitability factors when deciding between betting and checking ?

Thanks
