Scroll speed makes perfect sense as a "pre-determined number". It refers to the speed at which the UIScrollView scrolls. There is nothing nonsensical about scrolling the UIScrollView at a pre-determined speed.

@Claude31 It's unclear to me how changing the frame of the navigation view that the the table view is inside of in any way addresses the issue. It doesn't work. Why didn't you at least try it before posting it here?
