I'm liking the leverage ratio though, that's close to my "holy grail" numbers I'd shoot for.

This is a useful explanation
Anywho, the linkage, the 'from the shock' point doesn't really matter, as it only affects the leverage ratio and shape (well, an important characteristic, of course), while it doesn't do anything for the anti-squat and anti-rise characteristics. So the rear axle point of view is the one that matters - QED, Commencals, Konas and the like are still single pivots, even though they use 'four bars' to drive the shock (unlike Orange, that uses a single swingarm, well, until recently that is). That's where the faux bar name comes from I guess, looks like a four bar, actually isn't.
Same four-bar vs. not-a-6-bar logic applies to the Demo, Enduro, Sender (and some others, like the Polygon e-bike) for the same reasons.
As for dropping off anti-squat characteristics, the instant centre defines it. It's easy to visualize it with links that are so close together (the IC is near them). Considering they are counter rotating, the IC travels forwards, which will of course mean the AS will be dropping off (the further forward the IC is at the same height, the lower the AS will be). Without doing insane stuff with chain tensioning, I don't think it's possible to have a rising antisquat characteristic going through the travel (could be wrong, correct me if I am), so the only question here is the rate of the drop-off.
The reason for my comment of AS dropping off a cliff? Short links tend to have a large angle of rotation to achieve the desired movement. A large angle of rotation usually means large movements of the IC through the space. That can also mean large changes in the observed characteristic. Longer links keep the characteristics more constant. Case in point, Neko's current DH rig (V2 low pivot) with a fairly long rocker link.
The thing is that's just one aspect of it all. Another aspect then is the frame stiffness, frame manufacturability, what kind of characteristics you desire to achieve, etc. It's a game of compromises. And a lot of it comes down to what the brand or the designer wants to achieve from the bike, what kind of 'feel' they want from it. Even who the bike is intended for as in what kind of rider and what kind of terrain, can play a role.
Not all Unnos are created equal!
That Unno has a face only a mother could love.
Ontopic: no high-pivot = don’t care! 🤪
Unno thing looks like my dogs dinner. Also bummer.

Not manufactured in Barcelona anymore but in Asia, same as the other coming models from unno, slight rebranding etc, trying to be more price competitive with new models but all the old ones are sold out anyways.
Also new component brand „Deux“ for bars, stems, both in one, and more shitty cable routing headsets.
And fuck me that bike looks like the result of an orgy between several ebikes, some thankfully unreleased Canyon concept bike, a stumpy evo, an evil and the main ship mast of the Royal Clipper.
