[NSRCA-discussion] F3A Judging / Scoring

[Dr Mike]

Speaking of.Earl can you attach the unknowns also.  I am trying to do this
and don't have the maze of the path figured out.

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. 

 

 

Earl
