Reputation question

[SteveG63]

I have a forum that is in it's 9th year and apparently, I have never paid much attention to the reputation manager and settings therein.

If I change the reputation settings (not the levels), does reputation get recalculated? For example, if I have 1 point for every 30 days on the forum and I change that to 1 point for every 60 days, does vB recalculate reputation?

Or once you get reputation, you're pretty much stuck with it unless you get neg'd by someone?

Thanks guys and gals.
