I think that sounds like a pretty well educated summary based on what's available out there.

FWIW that Coma mix still didn't have over half of the vocals done by the date on that DAT 2nd November 1990.  There were vocals completely missing and other parts with Axl saying:

"see and this will all be special effects shit"

Or another line

"when all I needed was clarity and somebody else to write some fucking words to this god dam song"

(at least I think that's what he said, I haven't listened to this in years and don't even know where the DAT rips are now, somewhere in the house lol).

So for example with this song most of the music was done by this date but the vocals were still quite a way from being finished.  Still fits with your timeline though, the bulk of the recording probably in mid to late 1990 and then final bits done by early 1991, then just mixing and little tweaks happening after that.

I would call Coma a Demo tho whilst stuff like Estranged were like the DAT's suggest "Rough Mixes" of close to the finished song.

fyi it's just a short clip of Coma with the lyrics not finished and a very early Jungle.

Not sure why these are being held on to. Most aren't going to care.
