Hello,
I've been interested in changing the rate at which certain skills increase and how much certain skills contribute to character level up. I've found all these actor values, but I haven't really found any clear explanation of what each value actually does.

Can anyone explain these values or point me to an explanation?

Skill Use Multiplier - I know this affects how quickly a skill improves when used (but the values are all over the place)
Skill Use Offset
Skill Improve Multiplier
Skill Improve Offset

Thanks!

Anyone?

This is largely guesswork, so take it with a grain of salt.

Skill Use Multiplier - This is how many times you are considered as having used the skill, which will result in a corresponding multiplier for experience
Skill Use Offset - Same as above, but linear increase rather than multiplicative.
Skill Improve Multiplier - Actual quantity of experience given per use of skill multiplier.
Skill Improve Offset - Same as above but linear instead of multiplicative
