Yes I agree, but once you have a vacuum you can engage the tube and lock it in. It is possible to do this manually during the field setup before the robot is enabled. We have tried it out and it works! If you establish a good seal with the tube, the vacuum will maintain for quite a long time. You just have to figure out a way to prevent atomspheric pressure from leaking back in at all possible openings HINT HINT!
The fact that although many of us disagree on specifics of how FIRST should conduct events, design a game, and facilitate as much fairness between teams as possible, in the end we still greatly enjoy each other's passion for FIRST and provide genuine respect for each other
