Sometimes the rep works more like a ladder on this site. It may be easier to reset it rather than adding to it.

Vets and vats would still give the rep, but make the rep power different. The rep power is based on post count, years registered, and rep points. Maybe next time adjust the weights of the rep power.

The amount of people to rep before you can rep again and the amount of rep you can give in 24 hours can also be adjusted.
