From what I've heard, M2AP is a far more effective penetrator than M61, though. I doubt that plate would have stopped M2AP at the same velocity.

That's mostly true. Velocity is the biggest factor in perforating steel body armor. Still, certain bullet designs can make a big difference. This same plate stopped five 50 gr TSX bullets at over 3,500 fps and one M193 at 3,369 fps, but was perforated by one 62 gr M855A1 at 3,251 fps.
