Shatner, my site is about 100 pages. I have been seeing traffic increase in a very phrase-specific manner. Traffic began increasing last Monday, when I noted a 10% increase. By Wednesday, it was about 50%. Then about 70% by the weekend. I'm still trickling upwards. I am popping into the #1 spot on more and more phrases (with sitelinks -- which I think is a crucial sign). I don't mind the gradual increase, but I do wish the spidering/caching would occur at a faster pace.
I have observed the testing that you mentioned, in the weeks prior to the big improvement last week. I would show up #1 for a phrase, for a day or two, then it would revert. That was happening for about a month it seemed.
