This is an interesting idea. Has anyone been able to get data about how much the pyramids change over the course of match play? They flex a lot and I've noticed the pipes routinely coming apart; I had to push some back together after every match I reffed. Does anyone know just pushing things back together enough to keep everything in spec once it's readjusted? Or would more work be required? Regardless, even doing it once would be better than the current way now.

I know we cleared all 8 quite well in a practice round, and were surprised the next day that we hit one, but I'm not sure what did it.

Re: Pyramid variation

One of the things I didn't realize until week two of competitions this year (the first week I had to assemble the field) is that the bar height spec is to the base carpet. There is a layer of masonite and a second layer of carpet on top of the masonite around the pyramid. That has thickness that makes the measured bar to carpet distance seem short.

Identical to this at Hub City.

If I remember right, the pyramids at Hub City were different heights. I believe the red tower was higher than the blue (I know from personal experience because I rammed the red tower with about an 1/8" of the top of our robot, and then cleared it (accidentally; robot got stuck) on the taller blue one. If I remember right, the red pyramid was the one that was 28 5/8" with the blue one being about 28 7/8" to the bottom, but don't hold me to that.
