Scoring Vs Judging

The other thing to remember is that every plane can snap about a dozen
different ways (depending on the pilot input and throws).  And on top of
that, we have pattern planes out there with some very distinct wing shapes,
sizes, and airfoils, all of which will make their snaps different.

At the higher levels, the pilots are actually trying to make their snap as
close to a roll as possible without being zeroed.  Unless it is an obvious
pure-aileron roll, zeroing a snap that isn't quite in the criteria is a
steep penalty for only a small amount closer than other snaps.  Most of the
cheating is done on snap exits (pilot will take out elevator and rudder
inputs before aileron inputs to finish snap rotation more on-line and with
the right rotation), and judges really should, imo, be much more critical of
the last portion of the snap than the snap itself, or the entry to the snap,
as the last portion is where cheating yields big rewards.
