Congrats,I know how hard that is to do.I have never actually done it,even when shooting up.
The first shoot this year I only had 1 or 2, 8's(mbr) but I only went to 2 more shoots after that and my shoulder problems just got worse and wasn't able to make clean shots or practice enough to maintain.
I really only shot strong enough to accomplish this for 1 season(open class)before I burnt myself out.[&:]
