The room opens this beat on its simplest reduction, at 120 BPM, and adds the notes back a rung at a time -- 3 of them. Nothing is a matter of opinion: each rung has a tempo to reach and a gate to pass before the next one.
Tempo goes 120, 140 and 160 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
