How you vote/flag is weighted in a number of ways.
I've certainly noticed that my own karma isn't strictly related to the number of upvotes/downvotes I get in a certain time period, (a day for example). Moreover is seems that posts that are heavily upvoted may not reflect on my karma for a day or two - in fact my karma seemed to be increasing due to a post I made about a week ago, even though I hadn't posted in the meantime.
I always figured that was some sort of anti-spam fuzzing (similar to what Reddit does) in calculating karma, but it's even better (IMO) if what you wrote is correct.
