One other data point that may or may have something to do with this (though I think we've already been clearly told that this was a bug; I just don't know if I'm a symptom of the bug or something else); in my regional Google, if I searh on regional results only, I'm back at the top. if I 'search the web' I'm still in the hole. I'm normally on top for both. So there's a clear difference between either the data or the algo between the regional vs web results.
