Dilla septuplets

This week, I went back to one of my earliest practices from 2017. When I started my studies at Sydney Conservatorium, I came across a rhythmic practice called Process Dilla 2. Which was a Septuplet grouping exercise created by Drummer Simon Barker. 

The exercise is laid out in part a)~e) which goes up to 5 groupings of 7s. I'm still struggling with the exercise as it has a constant pulse continuing with it and I'm still trying to figure out how I am going to play it on my Jang-gu.

Currently, I am practicing the exercise with my drumstick as it felt more natural with up and down motion. I found it very hard to find a breathing spot, although for me it was very similar to 4/4 when playing faster.
