The problem with averages is there is no real "one' answer if there's a great degree of difference in the dataset, if there was I'd be typing this from a beach with seven female experts as I would have applied it to stock market shares
The above won't help us with Sans Cardage tho, I still feel we should choose to make it visible to see if it's a problem first.
Not sure about regional and national grades either, I'd kinda like it be as even as possible as I tend to measure against other people in the same grade.
I think with the averages it's hard to judge as in WAFTA I'm currently a B same as BFTA, there is a 5% difference to the BFTA. Therefore AA is 80% here and 85% in the BFTA after yesterday's shoot I'm on just over 81% in WAFTA for the year which is a winter and summer grade, as long as I don't have a nightmare at the last one in two weeks I should then go up to WAFTA AA and BFTA A.
That is as long as my card goes in too lol
With regions having slightly different shoot rules to a GP, maybe it needs aligning throughout not sure if this is best or not. I'm also unsure what all the regions grade fresholds are.
