Double Hook/Triple Hook Yields (HW/ARR)

HW DH/TH yields:

Yield is based on gLvl and to keep the display simple, it’s shown by such. i180 - 210 are the same breakpoints as they are all the same glvl (180) on the backend.

Interestingly, this is the first indicator of something obviously formulaic happening with FSH numbers:
DH 3-4 = (DH 2-3) × 1.5

ARR DH/TH yields: https://docs.google.com/spreadsheets/d/1mdhJRw06H7jkNVYooFGl2LhmbO8u7x84J8VAgxudk0w/

Lowest (glv 2): DH 3 = 18, DH 4 = 27
Highest (glv 80): DH 3 = 348, DH 4 = 522

All follow the same scaling of DH 4 = (DH 3) × 1.5 observed in the HW fish.

For some reason glv 21 and 22 have some odd numbers relative to subsequent ones, but do follow the same scaling.

Gigant Clam has a hard gathering breakpoint and yields 3 at that rating (348) so it is impossible for it to yield 2.
