sounds like your coach was asleep at the wheel on this one. the 50% came in when the National Federation liberalized the certification rules and making it allowable for a wrestler to weigh in and wrestle one weight class above his certified weight. The question then became how to seed a wrestler at regionals if he had certified at one weight but wrestled most of the year at another weight. The 50-50 rule was instituted; notice it does not say how many matches must be wrestled, only what percentage must be wrestled at the wrestler's certified weight. Feel bad for the kid you are talking about, but you can't have your cake and eat it too.
