Thanks to those who suggested 0/0/5/0/0 for R-4 on the old Moonvine thread, I found that setup working for me in that RNG hell in 2 tries where 0/2/3/0/0 and 0/3/2/0/0 failed me.

That's it for P1. Not farming additional sealstones until P2 arrives, so I'll have an excuse to satisfy my 3-medal OCD especially in R-8.
