I've noticed the last 2-3 days that on duchamp sourcefinder that my daily movement was positive, then it was negative, and now it's positive again.

I was at rank 90 then I was at 88 but it said my rank change was -2. Then I just checked it and I'm at 89 and the number is positive again. I'm gaining on the person in front of me and the person behind me is some days off on potentially catching up to me.


Another thing that makes me wonder if I understand the Daily Weekly Monthly change. Are they all based on the current day going back? The reason I ask is it seems I'm gaining position but then one or both of the other are saying I'm loosing position...
