The beat the song is built on is one bar, played through bars 5-7, 9-11 and 13-15, and 3 more places -- 30% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
89 bars across 2 sections: 60 keep time and 29 are silent. The longest unbroken stretch of time is bars 1-60.

88 bars, about 2:19 at the written tempo. The course breaks it into 10 exercises over 5 sittings, about 25 minutes each.
