<R19> ROBOTS must be designed so that in normal operation BALLS cannot extend more than 3 inches inside the FRAME PERIMETER below the level of the BUMPER ZONE.
(emphasis mine)

But
Quote:
<G46> BALL Penetration Restriction – The BALL must not extend more than 3 inches inside the FRAME PERIMETER as defined in Rule <R19>. Violation: PENALTY for a basic infraction, plus a YELLOW CARD if no immediate attempt to remedy.
They really should have repeated "below the BUMPER ZONE" here, instead of just referencing <R19>.

Nevertheless, this is the way it has to be interpreted. Else, whenever an airborne ball went above your robot, you'd be in violation.
