In those files where the invisibility info was, there was credit multipliers too, so for easy accessibility, I'll list some of the stats. Since there'll be a lot of info, I'll spoiler it.
Basically the credits you get is multiplied by this amount, anything above 0.90 is good for moneymaking, above 1.05 and it's at the top.
