Kevin, that's what I was thinking you would find. All my VFDs act like that. In my experience, 60-80 SFPM doesn't make any difference. It's slow enough to set bevels.
I run my machines wide open too, but it doesn't matter exactly what SFPM they make. It's fast enough.
You're right about the differences between a 3 phase with VFD and... well, anything else.
The point is simply that the lowest speed gives you the most control, and if you can take advantage of the benefits of finishing an edge on high quality water stones, you'll understand why they are still popular and in very high demand.
