I have been intentionally trying to reduce my post-flop aggression lately, and my stats are now basically 3/3/3 flop turn and river compared to an average of 3.5 a couple of months ago. I think I am scaring too many worse hands out of pots and losing too many cont bets and probe bets to better hands.

I think being hyper-aggro on the turn is better than on the flop as it looks less like a cont bet. But I think you do it too much - it must become very obvious pretty quickly to an aware opponent.
