Couldn't you know how many rounds where fired and how much time a set of 100 took?
Here is a video that Jerry Miculek is shooting using some sort of timer for full auto (around the 2:30 mark).

Drrrrooooolllllll.
I have used the app SHOT TIMER and it will give you a count of the shots fired within a set period of time. If you know how many shots are fired within, say, 10 seconds, rounds per minute would be easy to calculate. It's free too. Give it a try.
