I know about the daily reputation cap and according to the answer in that question:
Any upvotes you receive after earning 200 reputation from upvotes for the day no longer award any points.
But look at Jon Skeet's reputation changes today.
From the screenshot, he stopped getting reputation for 10 upvotes (100 rep) and 1 accept (15 rep). i.e., He stopped getting reputation for upvotes after he had 115 rep.
But if you look at his reputation changes later, he still got 80 rep for upvotes.
Why did he stop getting reputation after 115 rep instead of 200 until later?
19 hours ago reversal Serial upvoting reversed
" in there. Could he have hit the cap but then fallen below it again when the serial voting was reversed? I'd expect that to re-run history though, rather than counting later votes.
