Mike,

In a junior regatta this summer an opti sailor sailed ocs to another competitor who was also OCS and crying to check on the kid... Of course the flag was up..
PRO dsq'd him.
He filed for redress and the sole judge awarded redress with average points.
PRO made the case for the sportsmanship award for the JO's.

Seems like the right thing to do all around... Not sure it goes by the book per your interpretation. Is there some wiggle room here.
