RE: Caller's Function
I agree- almost - being a Masters' flyer who FREQUENTLY forgets what he's doing (just ask ANY of the callers/helpers I've had THIS season) during a comp round, I *need* a caller...and he's announcing maneuvers at a different time than the judges need...so...my opinion....the caller is there for YOU.
Personally, I find if the caller has to holler a maneuver loud enough, and in the time frame for the JUDGE, then I don't want him there. It is a mental distraction.
And since I *still* cannot remember the difference between a Half Square w/ 2 of 4 and a Half Square with a 1/2, it becomes pretty important that my caller be able to "translate".
Finally - to "narrate" the full maneuver for the pilot is foolhardy in the upper classes, particularly FAI, where saying the manuever title takes LONGER than the manuever....
I strongly recommend a helper/caller that serves the PILOT's needs. The CD should see to the JUDGE's needs, IMHO. <flame suit on>
