This is a totally different scenario. Basic math could be done to show that a system using even just a few CIM motors would be able to lift quickly enough for a ten second climb. This is something you essentially can objectively prove *is* possible. The question mark was whether or not a team could tune a system to transition between layers smoothly and quickly.

That would be the area for a square cross section 6" per side, and as the diagonal of such a square would be longer than 6", it would be illegal per R3. The largest cross section available is about 28 inches, per the area formulae for a circle, pi*r^2.
Okay, so 27*pi square inches. I've seen vacuum setups work okay, but I haven't seen any using a 6" diameter circle that are strong enough to deflect a ball being shot into it. And honestly, if someone gets a ball up there onto their scoring mechanism *and* wastes the alliance's "dead ball" card on their blocker, I think they've earned the right to attempt to block a shot. I'd be more inclined to believe a 12" diameter suction cup with a well designed, high powered impeller could do it, but I don't see it here.
