Sorry but I made a typo...
My comparison was 240bps vs 200bps..
60hz (3600rpm/60sec)*4electrodes=240bps
50hz (3000rpm/60sec)*4electrodes=200bps
200/240=83% which is close to what we saw. We might have been able to improve the 50hz operation a bit by changing another parameter (gap timing) but that was outside the parameters for this test.

Most of the measurements were subjective except the total power throughput. We observed that operation at 50hz produced an apparent 20% less performance in arc length. This was checked multiple times by switching back and forth between 50hz and 60hz. Measuring the total power the system consumed also supported this conclusion and fits with the lower break rate.
