The beat the song is built on is a 2-bar phrase, played through bars 33-35, 37-39 and 41-42, and 10 more places -- 27.2% 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 and kick, counted in sixteenth notes. On its own it scores 41 out of 100 -- a fair first song -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 50 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 108 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 108, 126 and 144 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
