Changing attack equations in script

[Boba Fett Link]

Where are the attack equations in the scripts in RMXP? Can I change them without using the Alternate Attack Algorithms script? I want to remove the variance, ability to miss, and critical hit for a BABS game I am making.

The attack_effect method in Game_Battler (part 3).

Thanks!

I found and changed critical hit and missing, but I could not find variance. Do you know where it is?
