There's, realistically speaking, no way for me to "fix" the balance besides manually add an entry with a fake flight number to "correct" the data.

There should also be events to indicated requalifications, so I guess getting the correct qualification period should also be possible automatically without manual intervention (e.g. the below screenshot).

Either way I've been platinum for longer than the PDF export, so getting old data is going to be near impossible (I do have the flights logged in Flighty, but not the XP and miles movements), perhaps the import should only consider "complete" data, in my case 2023 and newer (since the first "XP Counter offset" in the data) - and warn that older data needs to be manually added.
