Why do they have similar classes like rookie comer and rookie Yamaha? Why not one or the other? Having 2 classes means the very competitive kids need to enter both. It doubles entry fees and reduces track time for all the other classes. If they combined all of these similar classes it would result in lower costs, be just as competitive, and everybody would actually benefit from more track time. I am probably missing an obvious reason why they have these duplicate classes, so please let me know.
