Impression Variations

[Dpeper]

My stat software consistently shows a 35-42% variation with what yahoo logs.

Its accurate with googles numbers when I use adsense? Whats going on? Any suggestions.

YPN shows less impressions? or more?

If YPN shows MORE impressions than your stat software it might be because you have more than one ad unit on some pages (just a hunch), because that is not fully supported yet.

If YPN is showing LESS impressions it might be that they are not displaying an ad on every impression. They ARE in beta afterall.
