What happens if a user with 15 Karma upvotes something, gets to 30 karma, and then removes the upvote? Does it remove the original two karma, or the new three? Or are increases in karma weight retroactive, so your two vote becomes worth three when you reach 25 karma?

It would remove the original two karma, and if you would vote again the new vote would be worth three. I.e. increases in karma are not retroactive.
I think this is broken. I tested it on a post of mine with 1 upvote (from me), when I removed the upvote it went down to −2.
