John, the Committee has extensively discussed this case and decided to apply the rule as written.
Flights for which the Duenna records an altitude exceeding the hard ceiling (General Aviation 18,000'; Golden Age 15,000') will automatically require the pilot to repeat the flight from the original departure airport—without penalty. (Pilots, at their own option, may choose to accept a penalty and go forward without repeating the flight. The penalty is 1 hour on the first violation and 3 hours for each subsequent violation.)
The rule does not penalize violations--it merely cancels invalid legs. Understanding that MSFS weather can generate severe weather transitions, the rule treats inadvertent ceiling transgressions as though they were computer failures—as something beyond the pilot's control.
The hard ceiling of 18,000 feet governs Modern General Aviation aircraft. The pilot who seeks to fly fast and efficiently at a high cruising altitude must judge the tradeoff between flying near 18,000 feet and flying somewhat lower to guard against unexpected air pressure changes and storm turbulence. The MSFS weather engine can produce very sudden weather events so this is a matter of real concern.
There is a risk-reward factor here: the structure of the contest allows the pilot to choose a strategy that makes the best time possible while not busting the ceiling.
We understand that you were not aiming to fly above the ceiling. This is not a matter of intentionally violating the rules. Let us be clear about that.
Instead, you were making a perfectly legitimate strategic calculation about the safety margin. You were cruising at 17,800 feet--a margin of 200 feet. You guess that the event occurred when you were away momentarily and were unable to monitor the weather continuously. All this seems within the range of normal MSFS weather fluctuations where unexpected altitude shifts of 200 feet or more are part of the way things work.
It appears that you took a "racing" risk here to catch the tailwinds and fly the Cessna fast and far. With no margin to spare, you executed a spectacularly successful leg. But in doing so, you inadvertently busted the altitude ceiling--making this an invalid leg.
You may re-fly the leg now. With favorable winds, it is quite possible that you might achieve a better time than the first ill-fated attempt.
