Tony,

Your rule proposal on noise has a penalty for being over the limit rather than a disqualification. I don't see why a weight limit could not have a similar provision. Assess a slight penalty for being slightly over the weight limit, a moderate penalty for a moderate violation. This would eliminate the crisis of being 51g over the limit. Rather than a tiered penalty like your noise proposal a mathematical formula could be applied to tie the the amount of penalty directly to the amount of violation. y=.5x^2 ? Something like this would barely penalize the plane that is 1g over the limit and severely penalize a gross violator.
