It all depends how it is built.. Lets say you build a rapid fire that the line is at 50ms to 100ms and default setting is on 1.00 in the speed multiplier.. 1.00 equals a 1000ms so take 1000ms and divide it by 100ms= 10sps.....if you take same example turn up the speed multiplier to 5.00 the equation would be 5000ms divided by 100ms = 50sps .... Hope that helps!
