If a wheel needs a little extra pull and speed, like an outside wheel, the Polaris system will not deliver, but merely let the wheel "ratchet" ahead of the mean average speed supplied by the one speed driveshaft system. Instead of a more sophisticated system which would "differentiate" speed and power requirements of each wheel....

I also questions on the "4x4 ADC" mode, but will hold off on that for now.....
