70 bars of 4/4 at a walking 77 BPM, 3:36 of playing, on crash, hi-hat, snare and kick.
48 out of 100, a step up from a first song, and the work is in how fine the subdivision is.
kick and crashes through bars 2-3, snare through bars 4-11, hi-hat through bars 12-23, snare through bars 24-30, hi-hat through bars 31-42 and kick and crashes through bars 43-47, and 4 more changes after that.
The beat the song is built on is one bar, played through bars 12-19, 31-34 and 39-41, and 2 more places -- 32.4% of every bar the kit plays. That is the spine of it; everything else is what happens around it.

It cuts the song into 18 exercises -- the grooves, the fills, and the joins between sections, which is where players actually come off -- and puts them in the order a teacher would.

77 BPM, in 4/4, with the time kept in thirty-second notes. The room plays it at any tempo from a quarter of that up to the written one, against the record where the record can follow.
48 out of 100, a step up from a first song, and the work is in how fine the subdivision is. The beat itself is 33 out of 100; the rest of the number is everything around it.
70 bars, about 3:36 at the written tempo. The course breaks it into 18 exercises over 5 sittings, about 26 minutes each.
crash, hi-hat, snare and kick. Nothing in the part asks for anything else.
