Arms outside of the 72 Inch Window

[SgtMillhouse648]

Okay,
Yesterday while i was watching the Webcasts of VCU and New Jersey, I saw a number of teams who's arms on their robots appeared to extend beyond the 72x72 inch window. The refs called penalties for ramps being deployed beyond the window if they were outside the home zone, but I didn't see any teams getting penalized for "over-extending" arms. I know our arm can be extended beyond the 72 inch mark, but through programming it will never extend beyond the window. Is there something in the rulebook I didn't catch excluding arms?
