I give that range because I don't know if Media Matrix counts multiple visits in a month as distinct visits or not. The number of pages is the smaller number - some pages require several requests to load graphics onto a page. Angeles National Forest non-region pages and Regions . Fallbrook pages in 1996-1997 and 1998 . All the plots show just a sampling of the actual data versus time.
Some weird things can happen in short intervals.
For example, the main page for some of the calculations I have done normally receives very few requests, but one week it had 2,593 requests, dominating all other pages. Also see Some older statistics . Go to Table of Contents for all of Tom's websites.
