I am not an expert on how the rankings are done, but each class has an individual who volunteers his time to compile the rankings. They are usually updated every two weeks or so. Early in the season, rankings are based on last years performance and information provided by the coaches. The rankers can only use what is provided them. They do not have the ability to go and watch every athlete wrestle. If you and your team mates are ranked at the incorrect weights, maybe when your coach submitted your teams roster, he thought those were the weights you were going to be at. As much complaining about rankings that goes on here, it is amazing that those individuals who take there personal time to compile them continue to do so. It is definitely a thankless job.
