Modern Robotics is an unknown quantity at this point

I think I found a typo in section 2.0. You wrote "Mode “A” (RUN_WITHOUT_ENCODERS) produced the least predictable and consistent results. The MATRIX motor has an initial dead-band," but I think you meant "Tetrix motor". This confused me for a brief second because there is a new legal ModernRobotics / Matrix motor.

The most disappointing part was the clipping of speed to 78% with the new controller and NeveRest motors. I was looking forward to the new controllers because I thought this was sure to be fixed.
The "clipping" is only in "Run with constant speed" mode and it is done for the very specific purpose of allowing the function to have headroom to adjust the motor speed in this mode. In this mode power (not speed) is limited to around 80%. There is nothing to be fixed. Running the motors in other modes will allow power setting up to 100%. See the posting on the FIRST FTC forum for an explanation of how the motor controllers really work.
