I'm thinking of tightening up in these kinds of spots (pf)

hrm. well, 2 hands definitely isn't enough - you don't have the sample because you're often folding those hands, i'd imagine. i had something like 500 hands (using my entire DB). the fact of the matter is: folding those hands is -50 BB/100. we're trying to find out which side of -50 BB/100 those hands really are. I don't think we need a 200000000 hand sample to evaluate.

Same filter. K9o, K8o, QTo-Q8o and JTo-J8o. In the BB. Put money in. 3 players to the flop.

Results are 104 hands with a VPIP of 100(!) and a winrate of (0.68)

So I may just suck compared to your postflop skills, but I'm gonna consider tightening up here as well.
