I agree, instead of clicking down or up one MPH at a time, for let's say a 5 or 10 MPH change, you get good enough to where you know the exact amount of travel on the throttle to get there in a split second. The biggest mistake I've seen people who have it and have problems with it is they try and accelerate up to the speed they want THEN engage the friction which is bass ackwards. The easiest way is to get around the speed you want, engage the friction, then adjust to the exact speed.
