The beat the song is built on is a 2-bar phrase, played through bars 17-23, 25-31 and 41-45, and 5 more places -- 29.5% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 21 out of 100 -- straightforward -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 28 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 102 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 102, 119 and 136 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
