How often is QS checked and/or updated?

QS fluctuates between OK and Great

Somewhere along the line, I got the idea that the QS was looked at maybe weekly or so, and updated accordingly. I'm not sure where I got that idea, maybe I dreamed it.

I am seeing instances where a whole bunch of keywords go back and forth between Great and OK several times a day. Along with that, the minimum bid is changing several times a day as well. It *is* a new account. But is this normal behavior? Has anyone else seen this? Did I just happen to come up with a set of words that are teetering on the edge?

I have a hundred or so words that are Great in the evening, and by the next morning, are back to OK. This has gone on every day for the last week or so.

Just seems odd.

Hmmmm - I still have not gotten my QS score in my account.
Am based in Europe, perhaps that is why.
Anyone else not yet seeing the QS in their accounts?
