Default Questions about chart difficulty

Does difficulty increase exponentially with speed? (If 1.1x is n times as tough as 1.0x, is 1.2x n^2 times as tough?) (or: if 150bpm jacks are m times as tough as 140bpm jacks, are 160bpm jacks m^2 times as tough?)

Precisely how does stamina have a general impact on ability to hit notes? How much does physical and mental fatigue come into it? Is fatigue also a thing that wears exponentially?

Given a speed of x bpm, at what speed f(x) is it so that x bpm jacks are as difficult as f(x) bpm one-hand trills? Can this generalize to other patterns?

Input from anyone and everyone is appreciated!

You'll have to define what you mean by 'difficulty' more precisely to answer any of those questions.

It's impossible to judge difficulty purely on speed or density of notes, imo. I don't think it's quite a linear factor, I think it would be approximately linear for low speeds but surely it must become exponentially harder at higher speeds - regardless, I feel like your skill level to play certain difficulties anyways is exponential (e.g. the difference between a SM 24 and 25 is bigger than a 14 and 15).

Like for example, a 140 bpm jack for 15 seconds might be harder than a 160 bpm jack for 5 seconds.

Honestly I don't think it's possible to simple scale difficulty by some function of rate, I think it would be better to recalculate difficulty with the higher bpm factored into the parsing algorithm.

EDIT: I'm presuming difficulty means difficulty to combo/combo with high accuracy.

Difficulty == skill needed to reliably hit a pattern (or whatever mina's definition was, that one)
