I think you got it close, without looking.
I remember seeing a lot snatched up in the 6 range, if I remember correctly, it went to 7 or so. Again without looking, so my figures would be off quite a bit.
Nor do I recall having that amount of notice on time of the split. Even so, if they had the notice, no one would be able to break even to get out.
