My suggestion is to make each District responsible for weighing their own kids in. Keep the process uniform for all 4 districts and have the District provide a ref and scales. In that, each District can run the weigh-in such as this. Check in at the District represented Official and have skin/nail/hair checked once thats passed pick up weigh-in card from district table according to Age group. Take weigh-in card to District run scales. Running it in this way the kids get in and out quickly and the weigh-ins run very smoothly. Very similar to how Park City runs their weigh-ins, which I believe they ran through about 1500 kids in about an hour for weigh-in last year. Multiply the process for each District and the process can be streamlined.
I have run all three of the tournaments' weigh-ins that I have been associated with this year using this process and I have to say that it is the most streamlined and easiest process I have ever seen in my son's 7 years in the sport.
If anyone in charge reads these and wants more information please feel free to contact me.
