The beat the song is built on is one bar, played through bars 73-88 -- 21.1% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.
It is played on crash, ride, snare, mid tom, floor tom and kick, counted in sixteenth notes. On its own it scores 58 out of 100 -- a step up -- and the thing that decides that is how much of it falls off the beat.
The whole song is 53 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
The room opens this beat on its simplest reduction, at 66 BPM, and adds the notes back a rung at a time -- 4 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 66, 77, 89 and 101 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
