The beat the song is built on is a 2-bar phrase, played through bars 17-23, 33-34 and 37, and 6 more places -- 29% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, snare and kick, counted in thirty-second notes. On its own it scores 35 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 53 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 112 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 112, 130 and 149 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
