Mad - I have noticed the same odd behavior. I can rank highly for a boat load of key phrases, yet traffic is virtually zero. I suspect it's similar to the propagation delay you see when you register a new domain and set up new name servers. I believe the latest results are still matriculating through the DC's. I am noticing an uptick again in the past few hours. I just hope the pattern of that past two weeks is broken next week. Hang in there.
