Now you are getting into the thought that people don't duck or change weights to avoid kids. I wish it weren't true, but lets not think for a minute that it doesn't happen. Kind of like 6 year olds don't cut weight. I wish that wasn't the case.
And as far time goes, 6 days is more than ample time for people to do these things.
As many questionable things that KSHSAA does, they don't have 3 regional brackets set and released a week before the 4th regional kids have to choose a weight to enter at.
