The cyclic rate of fire for a gun firing in automatic can be calculated if certain measurements are known.
Paramters:
(1) shot-to-shot time in seconds
(2) number of shots fired
(3) time to fire that number of shots in seconds
cyclic rate in rounds per minute =
= (60 / (shot-to-shot time in seconds)) - 1
cyclic rate in rounds per minute =
= ((number of rounds fired) - 1) / (time to fire that number of rounds) * 60
