These are photos of the tail of the board. In the first photo, I am standing on the board's basic position. You can see the bow shift slightly forward and move closer to the center of the screws. The bow also dips downwards. In the second photo, I am no standing on the board, causing the screws to extend fully. I don't observe any changes at the front of the board. It's worth noting that I am not very heavy, so the setup may allow for even greater sliding movement for heavier people.
