The beat the song is built on is a 2-bar phrase, played through bars 18-20, 22-24 and 34-36, and 7 more places -- 28.4% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, ride, snare, high tom, mid tom, floor tom and kick, counted in thirty-second notes. On its own it scores 48 out of 100 -- a step up -- and the thing that decides that is how fine the subdivision is.
The whole song is 64 out of 100, so the beat is not the hard part: what costs you is everything around it, the joins and the fills.
The room opens this beat on its simplest reduction, at 87 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 87, 102 and 116 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
