I weirdly know the EXACT groove you're talking about, lol.
I have quite literally spent an hour with a buddy ( @DsumDrums on insta) writing out that groove, and trying to understand exactly what's happening.
It's essentially 2 beats of a halftime shuffle, followed by a standard "paradiddle groove" at the same rate of speed. Kicks follow the right hand in the paradiddle groove. The problem is, it becomes a 20 note cycle, which makes the subdivision / time signature relationship very tricky.
There are numerous ways you could use math to describe and teach the groove, but being that its wildly abstract, I don't plan on tackling that one anytime soon, lol. It is needlessly complicated, but a fun trick to pull out. ;)
