@serps guy - I've seen that before...it usually means GA is overloaded or not functioning properly. It also indicates a lot of "dial turning" at G. Wait a day (or a few hours) and the data should update.
What I'm seeing today is traffic spikes followed by completely nothing (as viewed in GART). 9am and the site should be banging away, yet it's sitting at zero.
