Drop in EPC as of June 23

Anyone else experience this?

My EPC seems to have dropped off since June 23 on the day the most recent PR update Garbo took place. I'm not sure if there is any relation, my PR has remained the same as has the traffic and clicks I receive. It's just the EPC that has gone down.

Just curious if anyone else has seen this happen as of the 23rd. Smart pricing has been working so well for me so far, my earnings have been steadily increasing month by month, and then this. I hope it's just a temporary swing, this can happen from time to time, but I was just curious if others are seeing the same thing.

Hmm strangely, I eperienced a MASSIVE drop of impressions on that same date. I went from 4000-6000 down to 40-60. Traffic on the site is perfectly steady. This is one channel/site. The other tow channels/sites remain the same.

What could cause this?
