I think they use sampling once your traffic gets to a certain size, so though they report figures down to individual hits, it's not actually as accurate as that might imply.
Yes, it uses sampling. And the numbers might be way of. We had times, with stats fluctuating 40% if I look at the numbers from yesterday and compare them to the numbers taken more then 48h after the fact.

I've found that with GA the previous 24 hrs or so stats are not really accurate, especially with bigger traffic sites.
