I hesitate to ask this, since it sounds like a complaint, but it's curiosity and I can't find an answer from searching.
I'm stuck at the computer today doing some work I'm not excited about, so I'm taking frequent breaks. That means I've posted at least one question and answered several today. I noticed that when I looked at my reputation history this afternoon, that there were several events of upvotes, but no numbers beside those events.
Are there limits on reputation, such as how much it can go up in a day or how many votes an answer can receive compared to the number of votes for the question?
