[Jon Stratis]

It's a tough decision to figure out when a team is employing a strategy, versus when the presence of a disc is coincidence. Were I a ref (and I'll never be a ref, you have my word on that!), I would take into account past behavior of the robot/team... if they have many successful level 1 climbs without discs under their robot, and nothing obvious has changed, then I would probably consider it a coincidence. If, however, they had issues with the climb (not always getting all the way up, getting "stuck" with part of the robot on the ground, etc) in the past, it might be considered a strategy. If they spend time moving the disc, then it's a strategy.
