I was the MD for a USPSA "club".
We would have 6 stages set up on 6 different bays. About 30 to 40 shooters attended my match on a regular basis. I figured 3 squads was normally adequate. So I would start a squad out on stage 1/bay 1, then there would be a gap where stage 2/bay 2 was empty. Then the next squad would start on stage 3/bay 3, leave a gap, then the last squad would start on stage 5/bay 5 leaving stage 6/bay 6 open.
You didn't say how many people were at this match or how many squads or stages there were???
If you're pasting targets and resetting steel and BS'ing with your squadmates it does make the day go by faster.
