Is it fair to run 7 races a day in a week long championship?

See peter nelson's comments in the H16NA thread about top sailors missing races for some examples.

By contrast, The Tornado class limits championships to two races per day, at the OCR in Miami.. the class reluctantly agreed to a max of three for the class.

The reasons are ... breakdowns... If you breakdown and can't finish the day... you are out at most two races.. At the the 16 nationals... you could miss three races in just a couple of hours for a repair.

Secondly, A champinship should be about Peak performance...Sailing is not at its core a marathon sport.. Usually it's a game of skill, stamina and fitness. Starting at 8:30 and going to 5:30 is shifting the balance well over to stamina and fitness and less about peak sailing performance.

Opinions?
