@ Ravynne: Hmmm. Actually, the timeline is pretty much in line with your observations of actual game content? The timeline says that Vincent got shot approximately 23 years before FF7. It places Jenova's discovery approximately 30 years before FF7 (quote you're referring to: "Must've been about 30 years ago, when he found the corpse of an Ancient. He was elated!"). And given what we know about science in FF7, I don't think it's impossible that as soon as ShinRa dug Jenova out of the ground and decided she was an Ancient, they immediately started the human experimentation.
I like your observation about memory, though.

Disclaimer: I don't have the print version of the Ultimania to check, so I'm pretty much going off the sources available on this site. If it's copied wrong, then so be it, but I recall Tres edited it last December.
Some more explanation about the timeline: One thing that is important to notice is that the approximate dates (and approximate date ranges) are bracketed by exact dates -- and these are mostly accurate (except for one example*) when you work out all the math. I won't list all the examples, but if you sit down and work it out, you'll notice that it's consistent.
The first exact date prior to the Jenova mess is 1977, the birth of Azul.
The next exact date is 1980, when Gast leaves ShinRa.
That cements the start of the project (and therefore the birthdates of ASG) between 1977 and 1980. There's room to wiggle around within there, and it's certainly open to interpretation. A few points, however:
1. Addressing Tres: Sephiroth didn't remember the view from his room. He felt it was familiar. His exact words are: "... This scenery........ I feel like I know this place." This might just seem like word-wrangling, but there's a huge difference between getting impressions of familiarity and remembering (or misremembering) conversations. Sephiroth was specifically speaking about what Gast had (and had not)
told him ("Professor Gast... Why didn't you tell me anything? ...Why did you die?"), whereas when he's remarking upon the scenery, he's speaking of vague impressions.
2. Placing their birthdate at 1977 has the distinct advantage of not making Sephiroth 11-12 when the Wutai War starts. I know ShinRa gives fuck-all about how young their soldiers are, and I know Squeenix has a thing for young protags (hello, Zack?), but I prefer to wiggle my way up so that he's 14-15 instead if I have the room.
(2b. It also has the advantage of making him 30 by the time of FF7.
And 25 at the time of the Nibelheim incident.)
3. There are some inconsistencies in the ages from different sources. Genesis is said to be ~25 by the time of CC. If you put his birth at 1980 (which I think is pushing it), then he'd be 20. 1977 has the advantage of making him 23, which is close enough to be "~25."
I guess if you want to take the "approximately" part of "approximately 23 years before FF7" seriously, you can place Vincent's shooting anywhere between 1980 and 1985. I admit I take that one as exact, because it's not a round number.
*And that's because they didn't want to make a separate event for Rufus's birthdate. If you take into account the information from
Case of ShinRa, Rufus was born in 1982 (making him 25 at the beginning of FF7). This would explain the 1977-1982 date range given in the timeline (when in reality, it should probably be 1977-1980, with a separate event made under 1982 for Rufus's birth).

Crim's art is great -- he actually drew my favorite Genesis art
-- but I would not call it a "reinterpretation" of canon. He pretty much rewrites canon to make Hojo more sympathetic as a character and ... well, mischaracterizes Vincent in the process (in my humble opinion), but YMMV.
One of my friends says back in the olden days (before FF8 came out), she knew quite a few people who were Hojo fans. Apparently there were enough for her to call them "that crowd." I dunno where they've gone though. Onto better things?
