So, an 800 word internet article wasn't as comprehensive as you wish? The goal of the article seems to be "train your whole core and don't do traditional crunches and situps, which are bad for your spine."
As to posture in the study subjects, as you say, the majority of the population has APT, etc. So, you could go with the same odds for the article and the study and not have a beef, right?
Or, what if they had APT, PPT, or were neutral? Does that change the contention of the article, which is the core is not the abs, train the whole core, don't crunch or situp unless you make these modifications?
BTW, your own website just lists a whole bevy of core, ab and oblique exercises, without helping anyone analyze their "muscle balance" or posture first. ...and I think all those things I can click on are ads to sell books and dvds, right?
and put some shorts on this guy!
