It's surely true that you will more often have to "skip" targets that are visible from a location in order to "save" them for a later location where you have rounds to spare. That comes up with everything but PCC, but it comes up more often with more limited capacity. That's all true. I had to do that on 2 of the 3 stages last night. I'm not sure that's really an
interesting aspect of breaking down a stage, but you're right, there's more of that.
Stage planning with the higher capacity divisions doesn't have that particular constraint/consideration quite as much... but that just makes the other aspects of it more critical, since none of your direct competition has that constraint, either. Order of engagment, footwork, taking something on the entrance/exit... all that stuff becomes the pivot point, rather than shooting at a sufficiently deliberate pace to require no make-up shots and finding ways to avoid standing reloads. The revolver mandates a lot of stage planning, whereas a lot of other options are available with the higher capacity divisions.
Not more or less planning, just
different. At least if you're trying to be competitive. If you just want to get through the course of fire in some reasonable amount of time, then you can get away with less forethought with the higher cap divisions. Or you could just stay home!
Like I said, much respect for you and the other guys who can manage decent overall scores in view of the constraints. That's no joke!
