I think it is great practice.
There are really 3 matches in one.
Short range is 4 targets, 100, 150, 200 & 300 METERS. 5 shots each target
Long range is 4 targets, 200, 300, 400, 500 METERS. 5 shots each target
Speed Round is 4 targets, 100, 150, 200, 300 METERS. 5 shots each target, as fast as you can...with out missing. I think the record is at or less than 30 seconds for 20 shots including transition.
