From this bunch the one that gets me is the McCallum, Lucasfilm has gone to great lengths to portray the negative as being abnormally degraded almost lost (pieces maybe), yet he says (what i'm assuming could be an overall picture) a loss of 20-25 percent, that's not that bad. There's the Vader/Tantive picture Lucasfilm typically shows of the degraded negative which is all cyan next to the updated version, yes they are probably showing us a worst case or an example of how far the film had gone in one case. This number is a sign that maybe things aren't so bad. This quote came from a SWSE press conference i've never see the full thing of. Would love to find it.

The other two numbers though are at least close to some of the other quotes. but the 109/110 is GL sourced in both cases. The other two (800 & 748) are at least sourced from people closer to the production. And this number may mean that every SFX shot is a redo, all the way down to blaster fire, which we've been uncertain about. Need to run the numbers...
