The forms that we have used state the entered weight and the actual weight. Should not be an error here except for the person weighing the kid or the legibility of the handwriting.
I can't imagine the 50# mismatch if the entered weight was adjacent to the actual weight...would have been a red flag for someone.
Greg, I can foresee your 50 feet ahead of everyone as well as Michael....we've just not had any problems in this avenue. In Oklahoma they do desire that the arms are marked according to how they prefer. In Missouri they have the kids "check in" and have their arms marked. In any event things are sped up so incredible you can't imagine!
