Answered: In the climbing zone

For the purposes of applying rules SG7 and SG11. Please clarify that a robot on either side is considered to have entered the a climbing zone when any part breaks the perimeter.

While it seems clear to me, it was not to the referee at a competition last weekend who said that because he did not see a wheel touch the zone it was not in yet. I respectfully disagreed but wanted to get clarification in case this occurs at another competition.

This is correct.
