The beat the song is built on is one bar, played through bars 2-3, 7 and 10, and 17 more places -- 18.3% 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 ride, snare and kick, counted in sixteenth notes. On its own it scores 14 out of 100 -- straightforward -- and the thing that decides that is how often it moves around the kit.
The whole song is 35 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 57 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 57, 67 and 76 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
