Rapid Fire Grades

[Alex L]

I wonder if some of you can help me.
Here in Oz the most recent list of grades for Rapid Fire are:

Amended PA Rapid Fire Grades for 20 Jan 2005 M -- 575 A -- 560 B -- 525 C -- 470 D -- <470

Are these grade scores what the rest of you have been given?
Are Europe, Britain, and /or USA working on the same set of grades?

I recently shot my first competition in Rapid Fire, using a Standard Pistol (with a GSP). I had done a couple of training sessions beforehand, and found that the 8 sec and 6 sec runs had not altered very much - only a few points. However, the 4 sec runs were a different kettle of fish!!!
I used to be a good A grade shooter. Now I am struggling!
