Yes, those answers were passed on. What I'm taking away is this:

Realistically, regardless of the wide angles we sail, at the end of the day you have to avoid contact, and give time and opportunity for the give-way boat to avoid when you change course. So, although you have the right as in inside starboard boat (at the starboard mark) to do a Crazy-Ivan and fly over to the port mark, you'd have to be insane to try this in a crowd and expect to win a protest.

As for "at the mark" I'm seeing this for what it is. You're at the mark when your boat is there and you're going around the mark. Not a boat length away, etc. Looking at what Dave Perry said, the intent of the rule change (to "mark-room") wasn't to change the game, but to clarify who the "right-of-way" boat was (I wonder why they did this, maybe it has to do with collisions and damage?). Anyway, if you're port inside at the port mark, think of it under the old rules, you have the right to go there and make a seamanlike rounding, that's it.
