Scoring formula

Sat Jul 30 06:03:06 AKDT 2005

Bob,
         I'm with you on the feelings. Had a similar set this year.

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.

The problems and challenges that I am working on for next year's Nat's as 
follows.

1. Making sure we score FAI as per their rules.
2. Getting the AMA rules book or whatever to be clear on what should be 
done.
3. Getting XP supported software that will do both high/low and TBL. (FAI 
and AMA)
4. Publishing how it all works.
5, Publishing how it will all be done.
6. Printing a clear explanation of the Matrix system and how it will be 
used.
7. Making sure all Nat's attendees know what to expect before they get to 
the event.

Right now I am finishing up the equipment survey data entry, putting names 
to all of the photos for our web-site and the Nat's attendee survey results 
for the K-Factor.

Regards,

Eric.
