Thank you both!
I updated my G30 in the bed.g file to
G30 P15 X0 Y0 Z-99999 S8
and now, even after autocalibration I still have my Hayden derived arm measurements!

I had some time to think about it and realized my error. Duet web control lets you run the extruder upto a feed rate of 60 mm/s. I did a little math and realized that even my Mosquito Magnum can not support feed rates over 12.5 mm/s [1.75mm filament area = 2.404 mm^2. The Magnum can flow upto 30 mm^3/s. 30/2.404=12.48mm/s]. I was trying to calibrate the Nimble V3 for feed rates >400% above what it will never see! This will definitely allow me to lower my motor current, but I don't think it will help my speed problem...
