It looks like there is an error with Chris Voyer in: http://ortdg.weebly.com/rosters--ratings.html
He started at 1000, shot one round of 969, but has a new rating of 968.
I think the problem stemmed from the change of his starting rating. It looks like it was changed from 1000 to 967, but should have been changed to 969, resulting in a new rating of 969, after his round of 969.
If I were a TDG player, and I am, I would double check all my stats each time new stats are published. Oh, and I did. Now I suggest you do the same, TDG players!
