I believe Quick Erase is where the device ignores the oscillator frequency and performs the fastest possible erase.

Flash Magic always passes the oscillator frequency for the Rx2 and 66x, so its very likely that those erases are the normal erases.

P.S. We now have a Flash Magic discussion forum available at:
