Recognizing that finding anyone's ideal seating set up (which is almost always comes up short of ideal) is a slow act of discovery, I used Josh as an example simply to illustrate that one of BTB's first lines of attack would be examine the amount of dump he's got in this chair and that BTB would likely need to increase his. I never meant to suggest that Josh's seating posture was "a good goal to have" -- though for some it might be.
