My pitch recognition isn't bad but not particularly good either. When I play my mandolin, though, I can pick up small pitch differences on certain frets because I'm so used to associating finger position with frequency.
Not sure if you can reach AP (which is not clearly defined anyway) but you can dramatically improve pitch recognition in general by practice.
