This is correct -- there is no other way to quickly rifle through the patches. If you use 20-30% more energy to spin the knob you'll see it'll hop up to the 40-50's. x3 and you're at the end of the range. I was half expecting the misc params button to do something like this. For other knobs it shows the current position -- so it seams entirely feasible to have this impact the program knob differently. I think it's worth submitting as a feature request.
