the speed limit is just that a limit. It is an absolute number
That being said, most cops give you a little wiggle room. I would think 5 mph is probably what most allow, some maybe 10.
I like the fact my speedo reads about 3-4 mpg fast. So if I want to make sure I am at or under the limit, I keep the speedo at the posted speed.
