Villain is 25/22/15.6(3 bet) over 80 hands. Since he seems pretty 3-bet happy, I expected to take this down a fair amount preflop. I'm also happy to ship preflop and did not expect him to flat.

Although my 4 bet was defo on the small side for being oop this still leads me to believe he's not a reg or all that competent. His range on the flop though, is likely still pretty strong like [JJ-AA AK] Possibly AQ and TT if hes that bad, but I haven't got any relevant histroy in a 3 bet pot with him since this is the first time he's 3 bet me. Most of the 80 hands are from a different session and I've taken no notes so nothing concrete.

This is just feels wrong to me, but maybe it's okay other than the 4 bet being so small oop. Thoughts?
