Okay, I did some more tweaking on my calculator, adopted the thoughts from fishNphysician, and added another calculation for Halibut. It is not perfect for the Halibut (a little overweight for the shorter lengths and a little underweight for the longer lengths, but a good approximation overall).

So now for those who want it all, included are calculations for Steelhead/Salmon, Halibut, and Sturgeon.

Hopefully it will be useful for some. Take care, Fred.
