the answer is 200-500 rpm depending on the size of the nozzle and other factors.
here is a good article written by an employee of stoneage tools/ warthog. explains the science of controlled rotation water jetting.

here is the chart for the warthog nozzles.

i don't think i'm spinning at 300rpm's as i can feel the nozzles rotate. 300rpm's is 5 rotations a second.
when you get rotating too fast, the impact of the water is distorted. this turns the jet into more of a fan. sounds impressive like a high speed blender, but it's not very effective in cutting.
i've tried the rootranger at the roundup and was impressed. the design is pretty simple as it's pretty much a 0 degree rotary nozzle that's been turned backwards.
i use my rotary nozzle in a spray wand to clean the inside of pipes for a few straight feet.
