Is this just from self-testing or something more formal?
My last test I had about 800 pages in total, all pages were of the format:
http://www.domain.com/Category_Name/
http://www.domain.com/Category_Name/index1 - index5 (.shtml)
http://www.domain.com/Category_Name/8-Character-Code (.shtml)
I noticed the first 80 pages indexed were full from the last set, domain, category, 8-character-code.shtml. It was never the category or index pages that got indexed first.
