Bush Trips with landing challenge/scoring system

It would be great to have landing scores for each leg of a bush trip and then an average score at the completion of the trip. Maybe a simple score out of a hundred, instead of the ridiculously high points system used currently in the landing challenges.
Then different levels of achievements/trophies could be awarded (gold/silver/bronze etc…)

And PLEASE fix the issue where every departure of a bush trip is at exactly the same time.
