Well that ruined any thought I had of buying a DD.

AFAIK I get much better mileage than that, but then, if there is much
material to be removed, ie. a broken 3/8" bit, I will grind it
freehand, also, once the cutting edge is ground, I quit rather than
grind un till the whole end view is freshly ground.
