    The way I calculate cycle times in my head is to take 250 times the wall thickness of the part, which gives me a target cycle time in seconds. For example, if I have a part with a .100inch nominal wall, I multiply .100 inch by 250, which gives me a 25second cycle. If the existing cycle time is 25 or 30 seconds, then I leave it alone.
