It does not normalize the rounds.  One round can be worth more than another.  Easy vs hard judges, calm vs windy conditions, etc.  Especially with throw aways it's critical that all the round have the same "value".   


That said, I can see an interest in normalizing to the average score, rather than to the top score.  It minimizes some of the variance when a key flyer doesn't fly the round either due to a problem or simply choosing not to fly after winning the first 4 rounds.  Particularly in that last scenario, it makes the remaining rounds much more valuable to the 2nd and 3rd place flyers.

Well, it's normalization of a sort, in that it's a percentage of perfect within each class, so a 984 in Intermediate and a 984 in Sportsman mean the same thing, you flew 98.4% of the perfect score (no, I haven't seen a score that high! :-)   


Overall though, I don't like the dynamic of it.  It's very clear when you have a highly critical set of judges, everyone pretty much drops that round.  Normalization to best is definitely a superior way for people to see how they are doing relative to the best pilot in the round for a particular set of judges, regardless of how critical (or not) they happen to be.  An interesting experiment, but I wouldn't recommend it for future contests.

It is a misnomer to call what was used normalization. It is actually a reversion to the pre-normalization scoring scheme of yesteryear. The only difference from the old days is that by "normalizing" to a perfect score, you can immediately see the average raw score per maneuver.

So why the change in normalization?

Final data from the contest is also available here: 


http://www.patternscoring.com/560 , the per-contestant report is considerably richer than what you get on nsrca.us 



I also just completed an analysis of what would have happened if we'd normalized to best instead of to perfect, the only class where it would have made a difference in final placement was FAI Silver (MP15) where Jon's win in one round and 2nd place rounds were closer to Sean's scores than Dale's 2nd place rounds would have put him about 30 points over Dale.

That's not the scoring program, the XML says "Prelim", "1", "2" for the flight number, but the web server's transformation is showing it as "1", "2" and "0".

Everyone, 


The NSRCA website is back up and running again... our host was doing some maintenance on the server.  The scores for the Bakersfield contest have been posted and just to let everyone know... 



1.  Every score is normalized to PERFECT, not to best pilot 
2.  Every AMA class flew 2 final rounds  on Sunday  using unknowns 
3.  Best 3 of 4 prelim rounds were AVERAGED to produce a SINGLE round score to carry over into the finals. 
4.  Best 2 of 3 (prelim carry over + 2 final rounds = 3) count for the final score. 


In FAI F, Prelim carry over is shown as Round 1, Round 2 is first finals round, and round 3 is the 2nd final round -- for some reason the scoring program is showing that as round 0.
