Okay, one last question...are there any GOUT sync guidelines for these (particularly ESB and ROTJ), or just any general guidelines for how to make a good sync?

Yes, the sync delay offsets on Belbucus original uploads:

Star Wars (all mixes) +1.017 sec
Empire + 0.948 sec
Jedi +1.015 sec

It could also be worth mentioning that hairy_hen have since repaired a slight glitch in the PCM track of Empire (a high pitched sound appearing when the Falcon is "attacking" the Stardestroyer) and a glitch in the '93 mastering itself (a jump cut in the music just before C-3PO says, "If only you'd attached my legs, I wouldn't be in this ridiculous position." The music cue starts and then it seems to start again less than half a second later). The absence of the whining sound effect when the snowspeeder crash in the '93 remaster is still a little mystery.
