I went through LayDhammaFollower’s chart posted above and filled the slot that was open with “Kusala-mula
saṅkhāra (puñña abhisaṅkhāra with comprehension of Noble Truths).”
The same link above points to the revised chart.
P.S. @Dosakkhayo: The “ultimate two supersets” I commented on may not be what you had in mind. I was also thinking about whether that approach could be “too deep” for beginners. Please proceed the way you planned.
