The beat the song is built on is one bar, played through bars 41-55, 57-63 and 81-87, and 10 more places -- 28.6% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 38 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 64 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 125 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 125, 145 and 166 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
PRACTISE THIS BEAT →A one-bar groove on hi-hat, snare and kick, in 4/4 at 166 BPM, counted in sixteenth notes. It is written out above, and it covers 28.6% of the bars the kit plays.
Bars 41-55, 57-63, 81-87 and 89-95, and 9 more places. The time is kept on the silence to start with, and it changes 9 times over the song.
38 out of 100 on its own -- a fair first song. The song as a whole is 64 out of 100, a step up from a first song, and the work is in how many notes a second it asks for.
