Um, 70% at the nats is DEFINETLY an A class performance, no doubt about it. How many of the GMS shot 95% (2) How many of the M's 85%? (2) How many A's shot 75% (1)
Some arguments don't hold watter, the "I didn't shoot X percentage in a match," doesn't work. Time to move on You were in the top 25% of all the A Class shooters (at the national.) So, you beat 75% of the A class shooters.
Do you still think you aren't ready to move up? Nice shooting! Don't sell yourself short, and go nail some classifiers and don't be afraid to jump into a deeper end of the pool
