Say I want to move a turntable to "90" to line up some walls on the set. But, I don't want it to go more than 1 revolution to get there, and I always want it to move clockwise. So in the world of absolute encoders, where the reference is always 0 degrees, if the turn table is sitting at 392, it should end up at 450 degrees to be at the nearest "90" position. But math is hard. If the next time I run the cue it's starting from 360, I really don't want to rewrite the cue. Instead, I can set up a Dynamic Spike with a factor of 360 (degrees per rev), and an offset of 90 (how far I want it to go from the last complete revolution).
