I somewhat disagree. It would appear that giving it 83 either side of 127 only uses 65% of the resolution, but the power curve isn't linear, it's quadratic. A PWM value of +-83 applies 90% power. We simply max that out to 100%. So, we're using full range of the stick to control the first 90%, which IMO gives us more resolution where we really need it.
