Just noticed this, and I'm filing it as a bug although feel free to change it to
feature-request rather than
I was nearing my reputation gain limit for the day, posted an answer and received enough votes to take me "above" the reputation cap. My summary showed 7 upvotes for that answer, with 50 reputation earned. I refreshed the page and it dropped to 6 upvotes with 40 reputation earned and I'm now 10 points away from the daily reputation limit.
Clearly, someone who's vote counted towards my limit retracted said vote and their 10 points were taken away. I think a recalc would make more sense - I've clearly gained enough votes to hit the limit, wouldn't it be smarter for the system to figure out that I've still got at least 2 votes left to count towards my rep?
