What I found around is:
11+ = t1 = ~10% HQ rate
31+ = t2 = ~25% HQ rate
51+ = t3 = ~50% HQ rate
What I'm wondering is what effect does excess skill have?
I don't know how to correctly explain it in english, allow me to make a couple of examples.
Let's say there's a level 70 recipe and I have 90 skill.
That's 20 levels above the cap, meaning I'm past t1.
It's 9 levels above the t1 requirement.
What do these 9 additional levels do? Would my HQ rate be slightly higher? (like 15% or whatever) or will it stay at 10% until I manage to hit 31 skill above the level, where the bonus becomes ~25%?
Basically I want to know if there's a gradual progression in the HQ rate, or if it's exclusively in tiers and anything in between produces no result.
Not sure if my question makes any sense D:
