Thanks. I thought it was obvious, but I messaged you the details.
Moving on! I remember TBK had an upgraded auger. I have corrected the flexing problem at high torque to some degree (The spring end no longer damages the mag housing). The Goldilocks zone of 100+ still seems to be at 83% @4K though. I have a plan to correct this, but if TBK has already done the work in stiffening the auger spring it would save a lot of time.
I have had 95% at bursts of 50 or so.
