I had a chance to shoot a few IPSC and IDPA matches (club level and sanctioned) in TX and CA. I noticed that, although people have the same classification, there's a proficiency difference between, say, the A/Expert shooters in TX and CA. I know for IPSC it is nationally averaged and for IDPA is time based, so there shouldn't be much regional difference, but I feel it after a few matches.
Do you feel this too?
