Height of overpass

The fields usually don't maintain the exact specs for many reasons, damage, settling, changes to ease construction, sagging.....

Plan for it to be the correct but be prepared for it to be a bit off.

FIRST explicitly says to expect changes of up to 1/4". This is due to different crews setting the thing up. (Trust me, it's harder to set up a field than it sounds.)
