Ebay strikes again!

OK so how does this work?

My ebay rating, the stars bit, WAS 5,5,5,4.8. That's reading top to bottom.

I log on this evening and it's changed to 4.8,5,5,4.8.

The number of people leaving feed back has DROPPED by 1.

I can't see anybody missing from the feedback lists, so what happened to the missing feed back?

Is it just based on the last twelve months, so a buyer/seller from just over twelve months ago has dropped out of the statistics?

I don't think that's it George.

I know if a buyer is deleted/stopped from trading by ebay their feedback disappears, but no body seems to be missing!
