I would expect PA to be spec'ed to the "normal" dimension, which would be the PA of the cutter rack form that generates the gear. But a designer has the privilege to make it anyway he chooses, which may be more of an effort to make the part proprietary than to adhere to good design practices - just an opinion.
Other opinions? Anyone?
