Whats the fishing skill formula?

Question

I'm trying to find out the formula for fishing skill:
both "from skill X to Y you need Z tries" and "you need N tries to next skill".

I found a website called tibiantis which has a fishing calculator, but i would like to know the formulae.

I remember seeing the formulae in 2019-2020 in tibiawiki fandom, but nowdays I can't find it, I guess it disapeared.

The formula is not "20⋅1.1skill−10". It looks like you blindly copied-and-pasted the formula and didn't even bother to check if the formatting in pasted content made sense. The formatting of correct formula is 20⋅1.1^skill−10.
