Looks pretty good. I didn't realize Tranq benefited from EmpRej, but logs confirm you are right.
With 4t9, Insightful should provide some HPS (21 Int, and int is showing .32 HPS with 4t9).
There is now an 8% BoK (Drums). Probably an issue on Wrathcalcs, too.
If tabs like Regrowth would show min/max non-crit, min/max crit, and min/max Living Seed, it would be easier for people to compare the spreadsheet with logs, and find bugs (either in the spreadsheet, or in their input to the spreadsheet).
Glyph of Healing Touch is additive (subtractive) with GoN. So HT formula should be
... (1+.02*GoN-if(GHTActive,.5)) ...
Reference is
here.
For tank healing rotations, I like to assume that on average, Rj and Rg is refreshed a bit late (so perhaps the Rg is cast, on average every 28s, and Rj is cast, on average, every 19s, currently). The only way to not be late is to sometimes not be casting (or to clip a HoT).
If using a Lb3Slow, I assume that the initial cast (after the bloom) is a bit late, and that one of the two "refresh" casts is an entire tick too early.
If someone has Glyph of Regrowth, the tank cycle should be 8 ticks and roughly 25s.
In your first post in this thread, you misspelled "haste" as "hit."
