Yesterday I was serial downvoted on SO - top four marked answers. So, lost 8 rep and was sitting at #,#22.
Looks like the script caught it, because there's no downvotes for yesterday when I check the summary page. But so far, I've only gotten back half the rep - I'm at #,#26. I regained 4 rep.
Is this a bug? Does the serial downvote reversal perform a recalculation? My accounts are linked, in case does turn out to be a bug.
