The beat the song is built on is one bar, played through bars 36-42, 55 and 71-77, and 1 more place -- 23.7% 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 hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 67 out of 100 -- demanding -- and the thing that decides that is the speed of the hand keeping time.
The whole song is 45 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 78 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 78, 92, 106 and 120 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
