Maeran, what I do is take the LATEST report that you submit. So if you want to submit a new report with the same no of hours and sorties as before but with the new aircraft data and squadron data then that is the one I will use. The report must have the total hours and sorties for the pilot as reported by WOFF. The difficulty comes if, like myself, you move squadrons and go to a different region with a different score per hour. You have to keep track of that yourself. In any case, the total hotspot + medium + quiet hours must equal the total hours.

You are not allowed to change your difficulty level (A, B or C) because it is then impossible to calculate your points. If your pilot dies you start from scratch and then can change that level. Well, we would have to ask the SWO about that!
Good luck for when you get out of dock!
