Setup
As disc swings, cup follows
Mark moves behind the disk, moving cup around
If the disc gets out and back to the other handler, C1 should try and stop the further swing by containing that continuation
If the disc gets across the cup should all move to get towards the new player. This is the only swing where the cup can break a little bit and don't need to move as a group perfectly
Setup far side, much more straight up on the mark forcing the disc to the far sideline.
