The key here is that the Crawl Team has their own algorithm. It determines how frequently and how deeply to crawl each site. There are many factors involved, including the strength of the site's backlinks and PageRank, how frequently existing content has changed, how often new content is added, how much computing poweer is available for the crawlign at the moment, and probably a lot more that I haven't heard about.

How often is googlebot coming to your site now?
