The beat the song is built on is a 2-bar phrase, played through bars 5-12, 17-32 and 37-44, and 1 more place -- 66.7% of every bar the kit plays. Learn that one and the song is very nearly finished.
It is played on ride, snare and kick, counted in sixteenth notes. On its own it scores 50 out of 100 -- a step up -- and the thing that decides that is how many notes a second it asks for.
The whole song is 58 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 105 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 105, 123 and 140 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
