Around here, pin-down hole-down generally means the
Rico layout. With your PAP, it would put the pin 1 1/4" directly above the grip center, the CG at 4:30, and a weight hole 6 3/4" from the pin on a line through the CG. The low hole raises the bowtie to avoid flaring over the finger holes.
The reaction is supposed to be early (owing to the low pin), smooth, and continuous. It shouldn't be jumpy on dry backends and shouldn't be inconsistent on spotty backends.
