I lose rating by winning on time?

It looks like the dialog used the wrong starting rating: your last 3 daily games ended on the same day in October, and apparently the dialog pulled in the 1052 rating and calculated the difference between that and your new rating, but the rating formula used the appropriate 1021.

oh, ok, that makes a lot more sense
Is this a bug?
