So it could well be that a C ends up shooting too well for C or even B.
Changing that system might (I don't know the details) be a lot of work but if the data (score and date) was stored in a database rather than a spreadsheet it would be perhaps better to have grades based on 12 months or 24months (pick a number) which could change the grades without changing the boundaries or setting bands based on percentages (e.g. top 25% = AA, etc).
I am happy to offer my help with the computer side of things if anyone needs some help.
Its a rolling 20 niel and no the scores can be years old and essentially out of date. That was my case until recently
my rolling 20 as of Gp 4 included scores from 2009 and my % was 81%.
After gp 8 i still have gp8 from 2009 on ther (65%) but currently my average is up to 85.75% (i think0 so heres to hopping i can do better than 65% a week Sunday
I consider my 2010 and this years scores to be a more accurate reflection on my current ability to hit targets.
