I think the penalty of 5% XP reduction for flights where you get a violation per issue is too lenient. I think it needs to be far harsher maybe even 50% or even 100% of XP gained during the flight. This slows down players from getting to higher grades without actually following the rules. We could also have it stack if a player received 3 violations for their flight then they would receive a 150% penalty and lose XP from their tally thus sending them backwards. This would bring more value to the grading system and more reward for those who reach the top grades.
