That would be rare to have 7 D's and 3 A's. My boys are in 6 and under where this late in the season really nobody is a beginner or novice. Let a computer fill out the brackets so then nobody can blame human opionion and parents will not be allowed to mislead.
I disagree, there are a LOT of kids that are still novice. They will be in three weeks and will be next year.
Most of the bracketing done on computers is done based on human opinion...as in the separation criteria defined by each tournament sent in with each registration. Many times this is used to separate the kids within a bracket and not necessarily use to "seed" the bracket. For most, I believe separation is enough. I know others want to see their name at the top of the bracket, or opposite of that name depending on your situation.
If you are referring to the function within trackwrestling that allows you to seed according to your trackwrestling profile; I haven't seen many use this for seeding purposes. It's an interesting concept and one I could see that working, especially if all wrestlers had their results available...attended only TW events. I believe even this has it's own flaws and the only way to truly sort it out, is on the mat.
