It appears that the Team Version Rough Terrain measurements differ a decent amount from those of the official field.
In the Team Version document, they suggest making the blocks each 3.5" x 3.5", spaced 1" apart:
However, on the official field, the blocks are 3" x 3", spaced 1.5" apart:
The plate they are on also appears to be 50" long on the real field, giving some extra space on each side of the end blocks (while the Team Version base is only 48" long):
For teams that have built a Rough Terrain to practice on, have you been keeping true to the Team Version measurements, who did you alter its construction to make it more similar to the official version? Do you believe there is a noticeable difference?
