Default US contest scoring formula is broken

Interesting idea.

I think you might also allow BESTDIST to go to a non-finisher to throw
more points to the pilots who have great flights but can't quite get
home. The challenge is you can always go farther by flying longer. You
might need to also multiply by MINTIME/TOC for the pilot with the
BESTDIST or you create an incentive to fly WAY over MINTIME just to
devalue everyone else's score by racking up a bunch of miles This is
particularly true for someone who gets in a hole early. Since there is
no definition of TOC for a non-finisher, you could either set it to
the time at which the achieved their maximum distance on course or you
could measure their DIST as the distance they achieved within MINTIME.

Of course that's not simpler.

Hmmm, yes, reading the rules here... yes I think it's logical that
BESTDIST should be the best distance of the day, including non-
finishers. I'd stop there though. I don't have a beef with the
overall scoring strategy, just this little piece of it. I'll try to
find time to write this up with some real contest results as examples
and submit to RC. If it gets traction, they can put it on the poll at
year's end.
