This seems to have flown entirely over my head:

QJM == Quantified Judgment Model. Other than what the acronym stands for, I'm still not sure what it is or why it's better, as this article never explains. The best short explanation I've found is "The QJM consists of two submodels whose interactions represent several battlefield intangibles such as leadership, morale, and training." [1]

WEI/WUV (that's one thing, not two, and if you try to search for just WEI you'll get nowhere) == Weapon effectiveness index/weighted unit value. [2]

It seems to me that this 2017 post from the same blog [3] is all but required prereading, with the problem that many of its linked sources (such as the one that might explain WEI/WUV) are dead and point to .mil domains that do not currently exist.

Christopher Lawrence took over after Dupuy. He explains the current state of their project in War by Numbers (https://www.goodreads.com/book/show/32824088-war-by-numbers). He brings this methodology to bear on some recent conflicts in America's Modern Wars (https://www.goodreads.com/book/show/22224145-america-s-moder...). Reviews have been very skeptical.[1,2]
