Indexed headset - repair or replace?

Does not result from headset that's too loose, it's from (quoting Sheldon who's quoting Brandt)

Some folks assume that the dents in headset races also result from impact, but actually that is not commonly the case. Instead, it has to do with lubricant breakdown. Jobst Brandt has an article on this site describing the process in detail.

This has the same level of unimpeachable superduper correctness as if it were Chomsky quoting Einstein.
