bridge specs

I'm concerned that the bridge specs may be incorrect. I played with the bridge in New Hampshire and there was virtually no horizontal slop. If you follow the blueprints for the angle iron channel on the bottom of the bridge (#A1), you end up with approximately a 6 1/4 inch channel around a 3 1/2 in (4 x 4) board. Not only is there slop, but because the horizontal faces of the angle iron are "inside", the rocking motion of the bridge causes these parts to "jump" on and off of the 4 x 4. It would "feel" right if the angle iron were reversed so that the horizontal side is outside, creating a flat channel approximately 4" wide.
