Any time I've asked to do so at Virginia or DC, even on practice day, I've been told 'no'. I don't know why -- it seems to me that it would only help all FRC teams if the FTA's made official measurements and then posted them for all teams to see.

Check out rule 5.5.7 (new for 2013)
The pyramids at Chestnut Hill were close to spec - about 28.75" from floor to the bottom of the low rung. At Hatboro-Horsham, we measured as low as 28.25". The same exact field (the MAR field) was used at both events.
I think the discrepancy is caused by how tightly the sides of the pyramid are pulled together when it is being attached to the floor. At Hatboro-Horsham, there were noticeable gaps between the corner pieces and the horizontal bars (e.g. the connector pipe was visible). At Chestnut Hill, everything seemed much tighter (virtually no gaps). The gaps would let the corner pieces sit at a shallower angle relative to the ground, causing the pyramid to "shrink" in the vertical direction.
