eCPM down since Interest based ads went live?

Anyone else notice something like this?

I don't have interest-based ads enabled (at first I was going to but then I chickened out) however I notice my eCPM is down on average about 25% in the last week. Is it possible that the basic contexual targeting system may have been affected by the new changes? Has anyone experimenting with interest-based ads noticed any positive/negative changes in eCPM?

I've seen a positive change, but I'd be surprised if your changes are due to the new system. ASA stated here that it's a limited beta.

Today has been awful for us. We are typically pretty solid and steady... but for some reason we are in the dumps today. Traffic is steady though... which is all I usually care about.
