Scoring formula

"Just as an FYI if you do "score lower" you do force the system to count the
next lowest score. So you would have the correct effect in a drop-high-low
system."

Hmm - pilot does a wrong maneuver (nicely) that's caught by only one judge. 
Scores are 10-9-8-7-0, an average yields 6.8, dropping the high and low 
yields 8, both choices are poor when the correct score is zero.

However, this may all be irrelevant for next years Nats if F3A is to also 
serve as the Team Selection event for 2007 (very likely, the Team Selection 
Committee Chairperson is selected and the process begins after the '05 WC). 
The AMA requires: " The finals contest is to be conducted in accordance with 
the FAI rules which are scheduled to be in effect at the world championship 
for which the selection is taking place". Also: "The AMA Competition 
Regulations does not apply to team selection contests. The only applicable 
rules for team selection contests are the AMA By-Laws and standing rules, 
the approved program details, the current FAI Sporting Code, and this 
document". All
this according to the AMA booklet entitled "World Championship Teams - 
Procedures Governing The Academy's Sponsorship of FAI Teams".

While there is latitude in the FAI rules for variations at the Nats, neither 
AMA nor FAI appear to allow this for Team Selections with the exception of 
"approved program details" which are the responsibility of the Team 
Selection Committee. It seems best to establish a procedure for both that is 
consistent with the rules, whether we like them or not.

>>I remember a Nats (a few years' back) when I *was* the toughest judge on 
>>the FAI line, both Prelims and Finals.  I know because the CD came up and 
>>told me "you're being too hard".  Okay.  After it was all done, my higher 
>>scores tracked the overall placements of the standings pretty darn well. 
>>I felt pretty good about that, because there were some pretty high-falutin 
>>judges on my panel with me!!
>>
>> Then I learned - quite by accident - that my scores HAD been tossed. 
>> EVERY round that I sat there, doing my damndest to be consistent, fair, 
>> and downgrade by the rulebook....in the heat and wind, only to learn that 
>> I DID NOT NEED TO BE THERE !!!!!
>>
>> Some stupid jerk actually had the gall to justify that by telling me 
>> "since your scores got tossed, that makes the other judges' scores more 
>> accurate". I didn't wring that guys' neck....but he also made it to my 
>> list of "persons likely to be left out of my will".... :-)
>>
>> Actually had someone ask me a couple years later, "Why don't you get 
>> certified, Bob?"
>>
>> I'll put my judging consistency and skill up against anyone's..... but 
>> not if it's gonna be thrown out later.  As difficult as it is to train,

>> their efforts in the trash????   Why bother to play at all, if there is 
>> no more value placed on someone's best effort than that?
