It depends upon what you (actually our organization) want out of tournaments. If you want to determine who is the best skier this day, the current format (one chance and done per round) is ideal. Performing under pressure is part of determining who the best skier is this day. If you want to increase your standings list score, alternative formats could be better. If you just want more skiing, alternative formats are the only choice. Each of us is entitled to our preference, but the format must be national (and therefore selected by the majority). If you want to compare scores for skiers who were at different tournaments, the current one and done format is as good as it gets. Nothing is perfect. There is also something to be said for "keeping it simple". Maybe alternative formats should be for fun tournaments only.
The one and done format was designed years ago. There was a period of time when the tournaments that I went to had so many entries that "one and done" was a necessity. I am old enough to have experienced those days. It is likely that Regionals and Nationals will always have to be "one and done". So, if you want change, talk to your region's board members and be prepared to have solid reasons for the change you desire.
