The beat the song is built on is a 2-bar phrase, played through bars 121-144 and 161-175 -- 22% 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 crash, ride, snare and kick, counted in sixteenth notes. On its own it scores 37 out of 100 -- a fair first song -- and the thing that decides that is how many notes a second it asks for.
The whole song is 42 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 116 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 116, 136 and 155 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
