When I say it’s “flawed”, I mean that frames are missing and the audio (at least in ROTJ) had to be looped in a certain place to maintain sync with the video.

And I repeat that it doesn’t matter what the audio on the GOUT is like, because one can still use the GOUT as a standard for which frames to include in any given release. The fact that the missing frames for RotJ are in the middle of a reel makes adjusting the audio a little trickier, but it can still be done in high quality with software that can stretch small portions of an audio track to maintain sync but leave the rest untouched.
