Should this have been allowed?

[Bill_B]

<G57> During the TELEOPERATED PERIOD, FEEDERS may enter LOGO PIECES onto the FIELD by using the FEEDING SLOTS or by throwing the LOGO PIECE over the top of the FEEDER STATION wall. LOGO PIECES may not be thrown around the side of the FEEDER STATION
Violation: PENALTY

This was the first thing I thought of when reading the OP. The field geometry would make it hard to interfere with anything but the side to the left of the drivers (square) without the feeder stepping outside the station to do it. If the game piece did not come over the wall of the feeder station, the feeder deserved a penalty. Even if the penalty had been assessed, it would not have counteracted the loss of logo completion score.

I must confess that I did not pay a lot of attention to feeder activities during the regional I just attended. I did see several more hand excursions through the slot than were penalized, as some were.
