Cycle time [ms] calculation

The equation in the last part of the video gives a shortcut to calculating cycle time in milliseconds from RPM. the equation states: cycle time [ms] = 120/RPM.

I believe that actually returns a value in seconds, not milliseconds. 120,000/RPM would give you milliseconds

or (120/RPM)*1000 for a more clear approach.

Yes it does generate a cycle time in seconds, however we also had previously discussed how to convert from seconds to milliseconds so that part shouldn't be a huge leap for people to take.
