Why do time increments have to be linear? If I was programming something like that, I might have a sequence that might look like: 1, 2, 5, 10, 20, 30, 45, 60, 90, 120 minutes (just an example).
Arbitrary jumps like this are hard to predict. Say, you want 8, so you end up with 10, then you press down and you go 9, then 7, then up to to 8. Some of the cheap PSUs have large and fine grain adjustments which seems hacky to me. What does work is acceleration the longer you hold down the button, but it has to be just right (if the acceleration starts too late it feels sluggish, if it doesn't accelerate at the right rate it feels sluggish or wildly overshoot both going up and down). Rotary dials work great as you obviously have have direct control of speed but I don't know how reliably they are 10 years later.
