The beat the song is built on is a 2-bar phrase, played through bars 10-11, 16-17 and 20-21, and 8 more places -- 33.3% 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 47 out of 100 -- a step up -- and the thing that decides that is how fine the subdivision is.
The whole song is 57 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 77 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 77, 89 and 102 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
