(4) The stairs will now award experience indefinitely, instead of cutting off after a certain point as they did before. However, since the exp drops as the climb speed increases, once you cap out the climb speed you'll be at a much lower experience award, but at least you'll be getting something, unlike the present situation at higher skill levels. Note: even though the experience drops as the climb speed increases, you still come out ahead, since by the time your speed drops to where you are below the old experience levels, you are past the point where the old system would have cut you off completely.
