Yes your are right, It seems at times that the certification rules, which are written to avoid excessive weight reduction. Have stipulations that are exactly opposite. Certification should not be broken unless the wrestler actually weighs in more than 1 weight class above his certified weight. The certification rule really should be more based on what you weigh not what weight class you wrestle.
It really is not that big of a deal as long as everyone understands the rule. It limits all teams equally.
I'm glad you brought up the point, all coaches need to understand this.
