120 is an approximation for the point when CHR goes from being as effective as skill/macc to only being half as effective on HNMs. For lower level mobs, that point will come at a lower CHR value.
For buffs, CHR is useless. Different songs need different amounts of +skill to cap; Victory March doesn't cap, Blade Madrigal needs +58 skill to cap, Minuet IV needs +12.
