I was there in April and the wear patterns are on the side of where it leans and not in the center because you get pushed to the out edge of the stair. Climbing the steps activates very different muscles than other spiral stairs in towers, it was a very strange feeling.

One molecule at a time. Reminds me of a Doctor Who episode.

Every stone staircase suffers the same fate eventually. Go to any (really) old church or castle and you'll see the same thing. I think colleges get it worse because of the consistent student foot traffic.
