Back up before the wiggle and calm down. Can't we have an open minded discussion about this without directly or indirectly insulting one another?
My opinion: I see S as changing course (turning down) continuously until she turns up (start of wiggle). To me, she didn't ever straighten her course before turning up to avoid. If you follow 16.1 as written, S cannot do that, as P needs to be able to keep clear. P was sailing a course to the weather mark, and took the stern (kept clear of) the prior starboard boat. S was rounding the mark, and turning the whole time.
It's easy to blame P for the whole thing, but 16.1 is a very important rule.
