Been doing it for over ten years. I run Tuesday Nite steel here in Mesa AZ, 4 sat. match USPSA Hosemasters, Do stages for both the area 2, SSMG3gun and only after great time do come up with a balance. There are no secrets just time. You start to get use to it. Everything that go on is just part of a normal day. If your close to shooting a stage and you get called to do something, go take care of it come back put your self do a couple get back in to the stage and by then you'll get called for something else, just part of the day and you'll get use to it.
