Did FIRST mess up the game element drawings?

Our team has been putting together the different field elements, and when we were testing our chassis on one of the obstacles, we realized that some of the dimensions are off.

In the game manual and other field drawings, the ramp leading up to all defenses are supposed to be 12 inches (1 foot) elevated at a 13.5 degree angle, connecting to the platform with the obstacle at a height of 3 inches. However, in the CAD drawings for the ramp, FIRST says to use a 48" by 10" piece of plywood, which would mean the ramp is only 10 inches long, and the angle at which the ramp is elevated is much more than 13.5 degrees.

Additionally, the drawings and sizing specifications for the rough terrain show spacing for 3.5" x 3.5" blocks as opposed to the 3"x3" blocks FIRST says will be used during matches.

Has anyone else notices these inconsistencies, or are we just missing something?
