Charm formula is correct based on over 50 hours of personal live parsing - Kayen
Charisma ONLY effects the initial resist check when charm is cast with 10 CHA = -1 Resist mod up to 255 CHA (min ~ 75 CHA)
Charisma DOES NOT extend charm durations.
Base effect value of charm spells in the spell file DOES NOT effect duration OR resist rate (unclear if does anything)
Charm has a lower limit of 5% chance to break per tick, regardless of resist modifiers / level difference.
