I don't have a link to share for Steve Hoggs' blog, but here's the gist of it.

One of his views of good position is that the rider should not expend energy holding up the torso, body balance should be used to minimize those forces. So like a skier in a tuck, you locate the butt rearward from the feet (BB axis) to ultimately get the cyclist center of gravity ideally over the BB when in a low position. For me with a lot of excess upper body weight that means a lot of saddle setback or a very shallow seat tube angle.

The test for this balance condition according to Steve is to ride normally in your low position (or your preferred position) and lift both hands off the bars when it's safe to do so. If your effort to hold your torso in that position is very low, that's very good.

At the same time, if at that moment you tend to slide forward on the saddle, you probably need a tilt up.

After that you adjust the stem/bar position for arm comfort, handling, and whatever else.

It's not my idea but I like the results. Maybe I just have a weak core, but this works for me. Forward saddle positions do not.

I agree with most of what you're saying, I'm just responding to you asking "wtf is it?" I hope this helps.
