You're clearly ignorant AF.
If you think that stage plans for CLASSIFIERS (which is your whole pointless argument) make a difference between 21 and 24 rounds in the gun, you are out of your mind. There's a reason you're stuck in C or B and are still on the struggle bus to A and it's absolutely a mental one.
If you think 21 vs 24 rounds will change your stage plan and strategy enough to effect score on a stage, you're again wrong. Ever heard of shooting over 21 rounds from one spot on a legal USPSA stage? Me either, but I have heard of people reloading while moving between positions which completely negates this ridiculously small difference in capacity.
Every single statement you have made is clearly that of a troll or someone with absolutely no grasp of the sport (or desire to learn). If you ask me, you need to try IDPA or Steel Challenge, you're not cut out for this sport.
