1600 – 5800 OPM appears to be pretty much the ideal range for an electric DA. The PC goes 2500 – 6000 (and is much less powerful than the BO6040 so that 200 rpm disappears instantly when you apply any pressure), the Festool RO150 (used heavily on German car manufacturers' paint lines) runs 2,000 - 5,600 OPM/240 - 560 RPM and the Cyclo is fixed at 3000 OPM.
The Makita's 180 - 670 RPM (or Festool's 240 - 560 RPM) is not as slow as it sounds because that's a forced orbit mode not rotary.
Lots of detailers use only rotary buffers. That's the big reason we see so many horribly swirled up cars on the road. Not saying it's guaranteed that one will always install swirls with a rotary, only that a huge number of guys out there do.
