Channel impressions don't add up

[voltrader]

I've started to experiment with channels, but they don't seem to add up -- literally.

I have two main pages, which are dynamic. I place adsense on them.

At the end of the day, the sum of the ad impressions of those two dynamic pages don't add up to the number of impressions from domain.com channel.

Any ideas why?

Hits from cached pages on search engines aren't in your channel stats... if you put a channel from google.com or yahoo.com or whatever domain they use for their cache I imagine you would see the left overs...

I've been using channels ever since they came out, and my totals still don't add up. :-)
