Or is it? I hate these percent-relative word games things...
- Let x = "num MWW"
- then "num CMWW" = 1.5x ("50% higher than x")
- x + 1.5x = 1
- x = 0.4
So 40% is MWW, 60% CMMW?
Of course as an arrogant computer scientist I think they're downright kooky for not basing it on the galaxy, but ce la vie. Presumably there's one of those too, and this just wins for boring social inertia reasons as much as for any technical ones.

Of course this doesn't really matter for the above musing since top/bottom would purely be conventional based on our viewpoint, but otherwise illuminating on the issue of understanding rotation directions across the universe.
I don't think I understand how your reply relates to the question either, though, because I was asking what it means to see other galaxies "from above" or "from below," when it seemed like that had to do with which direction they appear to be spinning from here.
Your answer is about what we consider "above us" or "below us," but we can still see a galaxy "below us" "from below" relative to it, if it (or we) are "upside down," and I couldn't figure out how we determine the orientation of "upside down" or "backward" for every other galaxy.
Once you have a few dimensions on a normal or other distribution there’s not a lot of content that’s in the middle.
