Powerful/Precision Hookset tooltip is needlessly confusing

[LlenCoram]

I don't think this is true, I use Precision Hookset when catching Thaliak Caiman, and they hit the line pretty hard, and pulls rod to both sides

It's "generally" true. So far all the fish I've been catching have been sticking to "precision for light, powerful for medium/heavy tugs." It's known that there are exceptions though.

Could also just be catching the big fish with skill alone. The tooltips for both Precision and Poweful Hookset say "Has no effect on some fish." I know generally that means the fish will get away but it's also possible you are just catching it through RNG
