I normally view the stats installed with WP but I also have access to the host's stats which differ wildly from WP's.
Thus for the last week of July (to July 31), WP's stats show 1822 'views' which I assume means posts inc. the home page?
By contrast, this is what I get from my other stats package:
Web Server Statistics for http://www.williambowles.info
Program started at Mon-01-Aug-2011 03:56.
Analysed requests from Mon-25-Jul-2011 00:00 to Sun-31-Jul-2011 23:59 (7.00 days).
This report contains overall statistics.
Successful requests: 703,065
Average successful requests per day: 100,447
Successful requests for pages: 134,355
Average successful requests for pages per day: 19,195
Redirected requests: 56,158
Distinct files requested: 394,878
Distinct hosts served: 12,238
Data transferred: 12.87 gigabytes
Average data transferred per day: 1.84 gigabytes
Some of this discrepancy maybe accounted for by files outside the WP db (flat html pages) but within the same domain and measuring 'hits' but surely not all?
