I'm curious why you are adjusting this on the fly.
Adjusting in the fly allowed me to find the settings I like for different conditions. I travel almost a mile on a county road before hitting the highway. My road is incredible bumpy and washboarded, I turn it down so it's less sensitive until I get to the highway. Most times I run it at 50% but if the road turn twisty I turn it up a little and play. In Eureka Springs we did the low speed parade through down town, I shut it off for more pedal at low speed. It started raining on us coming home on the interstate, the road got slick so I turned it down. Personal preference on liking the knob over preset buttons.
