Your stats dont matter after that sample size.
I really don't know what you want to accomplish with that 4bet preflop. Make him push? Make him fold? Play an outragously big pot? I flat call his 3bet.

PF: I mix it up PF, generally just flatting. On the flop I just check back, its a bad good flop for us but bad. We are syill going to get it in but give him a chance to bluff
