Everything Eric is saying lines up with my view on this as well. I used "overlap" as a loose term as mentioned. "Barging" is also not a real term for this issue, but most racers will know what this means.

What I find interesting is that many top rules experts have published articles on this subject. While most talk in terms that we are here, there is at least one that says if L let's W in, L can protest even if there's no contact. I believe there was a case or appeal about that, ruling as Eric and I state here (L will lose the protest), but I can't find it at the moment.

BTW, thanks for posting those diagrams.
