In all honesty, I don’t think adjusting by a frame’s worth that late into the movie would be worthwhile. When I did this, I often had to find the closest frame to align to, with a GOUT audio track as reference. Sometimes it wasn’t a perfect match and I had to go with whichever frame alignment produced a lesser echo.
If I added a frame at that point in ANH I would have to do something to contrive a frame’s worth of repeated audio anyway. It just doesn’t make sense and the end result would not be appreciably better for it.
If I were in charge of getting a mix ready to play in theaters with D+77, I’d feel confident in what I’ve already done.
