I'd like to bump this in order to find out if this is expected behaviour or not. According to comments posted by Grace Note and Michael Mrozek, after I've submitted a down vote on an answer, up votes should restore the lost 1 point when I reach the rep cap. However, this just isn't the case for me, only a recalc restores the lost 1 point.
Anyone can verify this by looking at my reputation for today.
I hit my rep cap today, along with 2 accepted answers that would have taken my total to 230 if it weren't for a down vote I'd given a poor answer. I was on 229 and continued to receive up votes that didn't count towards my score because of the cap. Later, I was checking out the
/reputation page and noticed the shiny new 'Trigger Reputation Recalc' button, so I decided to press it. When I revisited my summary page, I noticed that my daily reputation had gone up by 1 point, and this 1 point had been restored by one of the up votes that wasn't counted before the recalc:
You can see in the image that one of my answers has 6 up votes and 41 points. I know that up votes are supposed to restore rep lost through down votes left on your posts, but they don't restore the reputation paid to down vote others. Is this normal behaviour? Could I spend all of my 30 votes down voting, then exceed the cap by 3 votes and restore my -30 with a rep recalc?
