We are using the old urchin.js and are tracking 2 subdomains under the same profile. We have a “track subdomains” advanced filter defined (as per http://www.google.com/support/googleanalytics/bin/answer.py?hl=en&answer=55524) as well as 2 segments for presenting data in the reports:

hostname matches exactly subdomain1.domain-name.com

and

hostname matches exactly subdomain2.domain-name.com

When I apply these segments to our Top Content > Overview report, the All Visits total for PageViews does not correspond to the # of visits reported for each subdomain.

For example:

All Visits = 53

subdomain1 = 24

subdomain2 = 32

Is there any reason as to why we would be seeing this discrepancy in numbers?
