Submit a new run. Never edit for this.

While it's ultimately your decision, I strongly agree with the above post. All runs are part of the history of the game, even if they're obsolete before they're verified. Good mods shouldn't mind verifying obsolete runs. I've known people who delete their old runs when they get a new PB (even one where it was WR) and it makes me very sad. It's history getting erased.
