He nailed it. That's the core issue. When a user once to see his/her delay time to edit the only way  is to touch (breathe on it in some cases) the delay time button, which currently throws you sometimes in 20-50 ms off where you were at. The natural instinct to edit the display would be to push in the encoder button in, the delay time you're at flashes, and then you should be able to engage the fine tune encoder button to edit up/down in small increments. Not touching the delay time knob which is so sensitive to begin with and jumps off the charts. That would life saver.
