If 12/1/17, what is likely cut-off for matches included in their algorithm? 11/4?Later as in relation to Thanksgiving, yes, later as in a later date than normal? Not so much.
I was told several weeks ago that 12/1 was the target date (Friday after Thanksgiving weekend), and now with TennisLink showing a countdown timer that will expire at 12:00 AM EST on 12/1 that would seem to confirm that. Now we wait and see if that timer expiration changes and if when it goes "ding" the ratings are actually all there.
