Resetting every users reputation

[USAMustangs.com]

I've had User Reputation disabled for a long period of time. I now want to enable it and set every member's reputation to whatever it should be depending on their current stats. Those that are defined in the User Reputation Options in AdminCP.

What is the query to do that? And do you follow that by Rebuilding User Reputation in Update Counters? Because Rebuilding User Reputation alone definitely doesn't work. All reputations are still the same after trying that.

And I assume the query will be a manual query you run in AdminCP > Maintenance > Execute Query?

Thanks.
