I deleted my old post containing an outdated answer (10k+ only) since there's a newer and better answer, but I haven't lost my rep from it yet (110). When will that rep fix occur?
When will that rep fix occur?
Never, in this case. Reputation from deleted posts is usually recalculated within a couple minutes (5-ish), but you won't lose any from that post specifically, because it qualifies for the special treatment.
See the blog post Reputation and Historical Archives:
[...] if you’ve contributed something worthwhile to the site, you should keep the reputation for that even if it eventually gets deleted. “Worthwhile” here is defined as,
- A score of 3 or greater
- Visible on the site for at least 60 days
Your post had a score of 11 and was visible for 6 months before you deleted it, so you get to keep your rep.
