I deleted this answer, which had been downvoted once. I just checked, and it seems I have lost another 6 rep for removing it.
I never knew deleting answers removed rep. Can someone please confirm?
It's actually sitting at +1 / -2, which gives you
1*10 + 2*-2 = 6 rep.
Negative net rep from posts is always removed when you delete them, and positive net rep is also removed if the post is below +3 or younger than 2 months.
