Why does the state of Kansas not follow the National Rules?

Attending the Perry Tournament of Champions this year, as the father of a participant, and not just a fan, has really opened my eyes. I continually hear coaches and parents complain about how much this kid or that kid pulls, but Kansas sidesteps National rules designed to discourage massive weight pulling. Why do we allow kids to pull large amounts of weight, weigh in first thing in the morning and then fill up and be ready for the match 10 hours later?

College wrestlers weigh in just before they wrestle. National High School Rules have the kids weigh in just before they wrestle. Why does Kansas think this is a bad idea? I'm asking for legitimate reasons why we, as a State, are not following National Guidelines?
