Sorry for all the posts, I'm very opinionated on this topic... actually I'm very opinionated in general
Using only 1 event for state qualification rankings also provides incentive for teams to avoid early events. It is unfair to those teams located in the Duluth area that can't afford to travel. They only get 1 week after build season ends to make improvements (with no reference) while teams in the Twin Cities area that can't afford to travel, get over 6 weeks and the opportunity to see 254 and 1114 play, as well as many of their competitors who go to Duluth.
It's not fair no matter how you do it. I just think we should reward hard work rather than worry about being fair in a single aspect.
