I think that you are misreading the stats and its skewing your ranges simply because of sample size.He is 25/17 over 52 hands so he has raised 9 hands . The 3 bet of 13% only applies to hands where he was already facing a raiseso depending on the table he could only be making his 2nd or 3rd 3bet if it kept being limped to him.

Having seen you 3bet with AK is he really going too be stacking off with 99 tt JJ AJ AQ if you 4bet/shove?.
