Great news!
I just plugged those #'s into my simulation spreadsheet to see how things would work out.
The gear ratio 6.86:1 and the tire diameter is 24.9"
Just as a quickee check, it looks like 4898 rpm would be good for about 52mph. 1560 rpm would go about 17mph.
Were you doing any field weakening or making use of the reluctance torque? I'm wondering because according to the ORNL test, they got 5000rpm at 225VDC (bus voltage) - it's on page 75 of the 2010 Prius test.

At 376v, it was 4898RPM clockwise, and 4762 counterclockwise.
I made the bounces a lot smaller when you crash into the voltage boundary, so you can't notice it at all. IT just revs as fast as it can and is stable right at max RPM.
