G3: Use common sense. When reading and applying the various rules in this document, please
remember that common sense always applies in the VEX Robotics Competition.
From the red box of SG7:
In general, unless a Robot or Alliance is intentionally and blatantly utilizing a Hoarding strategy, violations of this rule should be rare.
In your scenario, does it make more sense to say they are directly blocking Blue’s access to a mobile goal? How do you know Blue is going for the mobile goal? What if they want a Ring in the Red Home Zone? It might make more sense to say that Red is blocking Blue from entering the Red Home Zone. Thus, no penalty.
