Nobody asked for it, but I decided to compare the 2008 Gary Fisher Wahoo (size large, blue) and a much more modern mountain bike, namely my 2023 Trek Roscoe (size XL, gray).
And since somebody got on my case last time, this is not intended to be a 100% flawless, accurate beyond a shadow of a doubt, authorized depiction of either of these bikes. I’m not telling you that they are the same bike just because they both have a handlebar. I just did it for fun.

LMAO this is great. I love that you’re still playing bikeinsights.com on hard mode, and also how friggin different these are. It’s like an American pickup from the 80s vs today!
I’m modeling a gravel build (modern frame) I’m working on and am comparing it to my ’97 Zaskar LE whose geometry I’ve also sketched. When the front axles are coincident, the upper headsets are within 3mm of each other; the front center is within 12mm but the new frame has a _much_ lower BB (something like 60mm). This results in a more upright seating position because the seat is lower w.r.t. the handlebars for the same leg extension. This leads into my question here: if your BBs are nearly coincident, why is there such a huge difference in the saddle location?
I think your last post was a lot of fun and I see no reason not to play with this idea for now, good on ya.
I know you’re not trying to model them perfectly, but not having the top tube and the chain stays more or less form a single straight line on your Roscoe there really makes something seem off. For chuckles I chose a 2023 Roscoe to compare on Bike Insights and it has the same issue. I guess it’s just connecting the top tube and seat stay to the top of the seat tube, might be the same thing you’re doing? Anyways not to criticize just a comment that it really makes the bike look different.
