Snap or not K Factor

Tue Aug 16 11:42:43 AKDT 2005

Here we are in yet another of the long strings about 
observing and judging snaps.  They come around about 
as often as seasons.

It's pretty clear that as a community we don't yet agree on the 
exact criteria for snaps;  or have the observation skills to 
interpret the airplane behaviour; (which is extremely difficult to 
do in the fractional second the maneuver takes) or the proficiency 
to match the observed behaviour to the correct downgrades.
Most of us can add to this list of issues.

Yet, those imperfect judgments for high K-Factor snaps 
continue to have a high impact on round scores.

How about reducing the K-Factor for snap maneuvers in
AMA schedules?   We still fly them, we still judge them, 
we still invest as much of our resources as we want 
into improving flying and judging snaps.

And.....when we get it right, <VBG> we can put the 
high K-Factors back in place.
