Manage repuation points given by "I approve" scales option?

[Speysider]

Negative rep is given from half of the user's Reputation Power. It will not work in the same way as positive rep.

To set the Rep Power (the amount of rep that can be given/taken), you are in the right place, scroll down slightly to "Register Date Factor." The next two options after this, also allow for Rep Power. Change these options, and these will be the Factors that determine Rep Power.
