Ubertube hanging rule?

[Carter12s]

I am unclear as to what counts as hung for an ubertube in autonomous. Does the robot have to completely remove itself from the tube or does the tube merely have be in contact with the pole. There have been a few rules changes to what counts as hung, and I was a little confused by this. I am writing the autonomous code for my team, and I able to get the robot to set the tube on the pole very reliably, but I have not yet programmed it to release. Do I have to do this or can we release the tube in the first seconds of teleop?
