[NSRCA-discussion] F3A Judging / Scoring

[Richard Lewis]

Earl,

Can you provide a link to the FAI F3A sporting code and/or the Maneuver descriptions for the 2011 sequences...I will google them when I get a chance, but if you have links you can easily post it would be easier..:)

On your topic, is there any basis within the written rules to justify a judge tallying partial points and using a roundoff method (up/dowm) to get whole points?

I know you have been to some international comps and we have some international judges on this list, can you or anyone else comment on how this issue is dealt with by others around the world?  It would be beneficial if the judging during the team selection (Nats) approximated the judging philosophies that will be applied at a Worlds Competition, to select pilots that would fare best when judged by the internaitonal pool of judges they will ultimately fly in front of.

The list has been  a bit quiet - maybe this will help. The Nats are just around the corner and include the F3A Team Selections. F3A scoring is different than AMA in that maneuver scores are recorded in whole points - no half points. But just what does this mean? Is every errant movement a whole point deduction? Consider the 1 point deduction for each 15 degree error guide - how is a 5 degree error scored? It's important that everyone be on the same page with this.
 
I suggest that while the rules require recording the score in whole points there is no requirement or limit as to the magnitude of  downgrades applied to individual errors by a judge. A judge is free to use whatever fraction deemed appropriate. Logically, a 5 degree error requires a 1/3 point downgrade, 10 degrees a 2/3, and so on. 
 
The 1 for 15 guide doesn't allow a "free" zone of less than 15 degrees where no downgrade is applied and, similarly, doesn't mean small errors of a few degrees are downgraded a whole point.
 
OK - so only one 5 degree error is observed for an entire maneuver, how is this recorded? Ask this - is there a whole point deduction, is the deduction even near a whole point? No - then recorded the score for the maneuver a 10! The rules don't require a perfect maneuver for a 10 - just less than a whole point deduction. OTOH - a 10 degree error only would be scored a 9 as it's nearer a whole point and would be rounded down. Half point deductions present a bit of a quandary (one mathematical convention is to round to the even number) and I don't use them for F3A. 
 
What works best for me is a 1/3 point downgrade for small errors which is consistent with a 5 degree error. I find this an easy measure to tally elemental downgrades during the maneuver and eliminates questions with rounding as the score is recorded.
