What if W ignores all indicators there will be no room for her and decides to take her chances because L is obligated to let her in to avoid contact. Based on what I'm reading here W's chances are pretty good they would be exonerated in a protest. All W has to do is sell that they where pinned by the RC and had an overlap on L. Clearly barging isn't an automatic loser.
I see you speak wisdom, o barge-ed master?
