Marc, I completely agree with everything you say (including starting final glide after sunset...). My grip is only on the requirement for the flight computer to be "certified". What's wrong with using SeeYou/XCSoar etc IGC files for badges and diplomas? I imagine much more pilots will be motivated to get their badges and diplomas if they could simply submit the IGC files from their flight computer, certified or not, just like OLC.
