I see this in a different way. I see Google treating us as like we fell down a flight if stairs. They allow you to come back up but only a couple stairs at a time and then you have wait and rest. Then you can go up a couple more. I bet your graph looks that way too. Your pages not selected graph probably is still fluctuating and gradually back to where it was months ago.
