Well, if you allow weight changes then why do you require entering in a paticular weight before the seeding meeting? Why not wait and enter everyone at the seeding meeting? It seems to me that this could a method of running from people in certain weights. I don't think you should be allowed to register in one weight and then when you see who is in that weight decide to change. What is the true cut off time for locking into a weight? It reminds of the final seconds of an ebay auction... does everyone scramble to get their final weight change in?
