I also overlooked 5.5.7 and believe it is very good news that team personnel can verify pyramid bar height.
However, I also believe that the simplest solution to pyramid variability would be an amendment to the playfield setup procedure for FTA's requiring a height check and adjustment of the base plate positioning. This change could help relieve teams of the need to perform ad hoc modifications to their robots that may otherwise prove to be completely unnecessary at future events. Just my .02
BTW,
I am available to assist with any field setup adjustments in Utah and Spokane...Just pm me..
