(I'm aware that this post sounds like a way of drawing attention to doing well recently. It's really not.)
If you look at the July 24th - 30th SO league I was at #1 (just about... by 6 rep!) That correctly shows the change from the previous week as being +1 for me and -1 for Darin.
But if you look at the July 31st - August 6th league I'm still at #1, but it's still showing a change of +1 for me. How can I be +1 after I was already #1 the previous week?
