The beat the song is built on is one bar, played through bars 27 and 31-40 -- 16.7% 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 hi-hat, snare and kick, counted in thirty-second notes. On its own it scores 68 out of 100 -- demanding -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 61 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 109 BPM, and adds the notes back a rung at a time -- 4 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 109, 129, 148 and 168 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
