Since it appears that you may have as few as 3 teams qualified for the prize and since all three of these teams got qualification help since the day was overcast (all three used solar power) and since a lot of people will be there for the final competition, maybe you should give the teams that pre-qualified but didn’t qualify a chance to demonstrate their climbers without any chance for prize money. They could be scored as if they had qualified. This would give these teams some reward for a year’s worth of hard work.
