The reason you need so many placers in 5A and 6A is because they are so weak that most of the solid teams will score a lot of points by having their 10 qualifiers. In 4A, there are so many great wrestlers over numerous teams that they slow down all the many placers that one team can have. That's why the state results at the end of the tournaments for 4A end up at like 100-110 for the top 3, and in 5A and 6A you see teams end up with 130-140 point totals. Just my take on it!
