Blather, rinse, repeat

Oh, I've totally trolled the game fora. I've found nothing.

But you may have just totally helped me out. You say you beat the game and THEN went back for the G report? After getting the G report, did you then complete the entire chapter again, (or at least beat the Dragonfly again,) or did you just get the report, save at the next auto-save place, and then beat the final boss all over again? Because my plan is to beat Nero without the 3rd G report and thus finish this chapter, then go back and retrieve the final report. But I wasn't sure if that data would carry over to the ending.

The saving system in this game is the most confusing thing ever.
