Some unwalked paths left, but I see no points in spending additional gems to explore, despite the fact that I can afford to; it simply feels like a total waste of resources and, more importantly, my time.

Down to continue doing this if desired, but tracked Epic rooms (320) have now surpassed tracked Ultra-Rare rooms (318). For those confused, this does NOT mean Epic rooms are more common than Ultra-Rare. I stopped tracking Ultra-Rare and below a while back as there is plenty of data on them.
Not a math whiz, but I reckon the Sentinel drop rates across rarities are within the expected variance range. If we were to continue to track all rarities ad infinitum, I believe all rarities would balance out to around 1.5%.
Anyone knowledgeable about variance calculations is welcome to utilize the data on my sheet (linked in OP) to make some guesstimates.
Common: 1 x Token of Yasmine
Rare: 2 x Torches
Rare: 1 x Token of Anu
Ultra Rare: 2 x Bone Trinkets
Ultra Rare: 2 x Torches
Epic: 2 x Token of Orpheus
Epic: 2 x Torches
If sample size continues to come in and Epics still heavily underperforms relative to every other rarity, then it is something that may need to be looked at.
It’s one of those check everything moments.
For all we know, rates are meant to be near 1.7% and the Epic is just dragging it way down.
