VPI 300 RPM vs 600 RPM Better?

I just hooked up the 300 RPM upgrade for my scout and I waiting for the no brainer improvements. Does it take some time to break in? So far it sounds restrained and veiled.

I strongly suspect that the amount of motor vibration varies quite a bit based on the position of the magnets in the motor which I understand is not very precise.

Small changes in the phase of the motor drive makes quite a bit of difference in how smoothly the motor runs.

You can probably do this by tweaking the phase shifting cap value but the easiest way for me is to use a computer to generate the drive signal using an inexpensive frequency generating software.
