Fx how many times do I have to tell you that because you can't call with certain hands OOP (and I'm not saying I can) that it means they are unprofitable to do so for everyone. Learn how to play them. Go through different lines you can take, look at every hand you have played this way. For example go through HEM and look at every time you flat called AQ in the blinds to a late position opener and then play them out using the replayer thinking about your opponents ranges and thinking what your best line could be.
Then practice it in game. You'll only get better at playing this spot if you study then practice.
As for 3-bet bluffing, just don't do it at 2nl/5nl and you'll never be making a mistake. No need at this level which is why your stats show what they do. The purpose of 3-bet bluffing is to obv take advantage of someone who folds too much, but it's so we can widen our 3-bet range against opponents who can perceive our 3-bet range. If they call too much and don't think of our hand there's no point. And that's 99.9% of the people you will play at this level.
Also it's no great surprise that 3-betting our top value hands will make the most profit, because we're doing it for value, they're the best hands and we're creating a big pot. Obviously 3-betting 86s will never show as much profit.
