I see, that seems kind of strange to me. I see that Paul Worsley is the POC on that PDF, so I'm going to email him to get a little clarification on this. I'll let you know what he says.
The high rotor has more magnet strength which will generate more torque so we gear up. This makes more heat and fade more over the run, so to try to minimize heat/fade we were reducing timing.
