I (almost) exclusively use the "Start (+30 s)" button to set time. It's very rare for me to microwave things more than 3 minutes (6 rapid button presses), I normally do 60 or 90 s. The microwave starts going as soon as the first button is hit.
I assume everyone talking about button presses has simply never used one with a knob, and so doesn't know what they're missing - it's a vastly superior time-setting UI for a microwave I think.
