Today I deleted an old Hub that didn't pass QA. I'd kept it around, without mods or re-submission, pending replacement by a new, much better hub. I submitted the replacement hub yesterday, and it passed QA on the first try. Though the now-deleted hub was "up" only for hours during QA, it strangely continues to have a score (67) that is dragging down my overall (Hubber?) score. The replacement hub, which momentarily has a score of 73 — which seems to be rising — is my only hub. I'm a relative newbie to HubPages. How come? Anything I can do about this? Should I even be concerned about it?
