If I run a simple site:http://myexamplesite.com/ search then there are many more pages from my site indexed. It's only when I add the asterisk that things change. It's not the number of overall pages indexed which is cyclical, but rather the number of pages in the supplemental index. I do notice a traffic difference of about +/- 15% between peak and trough, so the extra 1,000 or so pages added to the regular index (de-supped?) at the peak must all be low ranking and/or considered duplicate content for some reason.
