I think that if you told someone who had just made MB that they needed to shoot a brace of lower scores to work their way through the classifications then they may well laugh at you.
Brutal, but true.
The classification system as it stands works fine up to Bowman. But once beyond that, the badges (such as they are) stop meaning anything, and the scores begin to have a significance of their own. For example - a 1275 FITA is MB, but only 25 points more will bring you to the magic 1300. But not GMB, which is another 14 points on from that (ladies
compound scores). I can't explain it very well, but suddenly achieving a classification isn't the most important thing, it's on a par with the score. If you can drill out 1300 FITAs everytime then you're at a level beyond classification, even though you haven't got the official GMB.
Does that make sense?
