ChaBonusMod & ChaPenaltyMod

[Thalix]

Can someone please explain this in deep? I don't understand, the description makes no sense for me:

Merchant:ChaBonusMod, 3.45,
'Determines CHA cap, from 104 CHA. 3.45 is 132 CHA at apprehensive. 0.34 is 400 CHA at apprehensive.'

Merchant:ChaPenaltyMod, 1.52,
'Determines CHA bottom, up to 102 CHA. 1.52 is 37 CHA at apprehensive. 0.98 is 0 CHA at apprehensive.'

Nvm, got it. If you want to cap at 132 CHA with a Bonus of 4%, you need

((132-103))*((-(x/(100))*4))=-4
= -(29x/25) = -4
x = 100/29
x = 3,448 = ~3.45
