Hi, new here.

Basically, I've noticed that the UESP has formulae from the games that aren't scripts - for example, spell cast chance, skill increases, etc.

Where do I find these and how can I edit them?

Specifically, I want to change (Spell's skill * 2 + Willpower / 5 + Luck / 10 - Spell cost - Sound magnitude) * (0.75 + 0.5 * Current Fatigue/Maximum Fatigue)

to

to(Spell's skill * 4 + Willpower / 5 + Luck / 10 - Spell cost - Sound magnitude) * (0.75 + 0.5 * Current Fatigue/Maximum Fatigue)
