Yeah, my machinists older mill on which the WW was done had a 6000rpm max spindle speed, but they used 5000rpm since they didn't like running the mill at top speed. They don't have a production mill though which can do >10000rpm spindle speeds, and their highest spindle speed on their newer mill is 8000rpm.

In any event, I think it took them around 25mins to do the entire base, which included the drilling of the holes, the O-ring channel, the tapping, and the milling out of the end-cavities, so 5 tool changes included in that. All up, 16.8mins, plus inter-channel moving sounds about right.
