I am a group 3 because of my business. I am classed in the same group as Jimmy Spithill. Really? This pretty much knocks me out of crewing on any amateur only event. I am talking about going sailing and not getting paid. Disqualified.
I think it should be performance based, and the rules should account for those who are paid a daily rate to sail vs. those (me) who work on boats, race boats, occasionally coach crews, etc. I think it could be a simple % of income. If you get say 80% of your income to SAIL (not sand, sew, splice, etc) then you are a 3. If you work in the industry, you could be a 2. That way each class can set rules on how many pros, Minor leaguers, and amateurs can race. If I built Bats and Gloves and was a batting coach for a local farm team I should not be classed the same as A Rod.
I thought merely working for a company didn't put you in group 3. However, the coach part would even if it is occasionally.
I don't think this answers the OP questions. But this has been my concern with todays World Sailings definition of "Pro Sailor". I sell racing sailboats therefore I am a Cat 3 pro. I also sell Sport fisher power boats and do not know how to bait a hook. Under this example I am also a pro fisherman. This is why I feel the local fleets should define and determine the pro status.
