Having been around on Wednesday to help setup 2 practice pyramids and see the field pyramids set up as well, I have one theory as to their height variation. When assembled, the multitude of slip joints do have some slop/play in them. The four legs can be allowed to flex/spread outward, or can be forced inward before their location is fixed on the floor by the wooden inlays, carpet, and tape. This can lead to some variation in the horizontal bar height depending on how much they are or are not allowed to spread. In KC the legs of the pyramids we helped with were cinched inward with a winch strap all around before the foot flange locations were set, and these crossbars ended up very near the 30" to center spec. The crossbars we saw in Hub City were all significantly lower.
