Google Crawl to Update Frequency?

[nube]

hello.

just need to refresh, used to be that google updates were 2 months between,
meaning: two months ago crawl would be this months update, next months update would be one months ago crawl and so on,
i undestand the refresh bot keeps refreshing but just the main pages,
is this still the same or did this change?
thanks

Our cache page on WWW2 is Feb.14.
It is updated every month near the beginning of the previous month.
