The beat the song is built on is one bar, played through bars 21-28 and 37-52 -- 27.6% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on hi-hat, snare and kick, counted in thirty-second notes. On its own it scores 50 out of 100 -- a step up -- and the thing that decides that is the independence between the hands and the feet.
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 74 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 74, 87 and 99 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
