Dave,
There you go again - getting 6BMike all riled up!
Here is another perspective on Sustaining Lag. Sustaining it requires that you have the "perfect" geometry and physics. So in that sense - it encompasses "everything" and your ability to acheive it - is measured everyday on that long winding road in the pursuit of golfing perfection. Hey, and if you are on that road and you pass 12 piece (ya, he'll be on the side in the ditch! Ouch!) say HI!
