I see the need and understand the points Rick made, but..

I dont like it when SI's diverge to much from the "standard". It's impossible to read them onboard, as there just isn't time to check them underways on bouyos racing. So you must memorize all exceptions to the 'standard', and remember them in the heat of racing. Not something I find easy. Here in Europe we also get them in different languages, so the possibility for a real disaster is there if the SIs is written in your third language or a language you dont understand at all.

There is a conflict of interest here, between sailors and the RC, but I dont see a good way to solve it.
