I think that there is waaaaaaaay too much emphasis on binding placement. If your weight is centered and you are standing on your entire foot. If you can wiggle the toes of both feet throughout all phases of a turn, you are probably centered. If in your video analysis and MA you see your heel and toe rotating an equal amount around the point where your tibia intersects with your foot, you are probably centered. By being centered the ski will act predictably and you will have the greatest range of options available to you.
In the product development process each major manufacturer has a team of developers. I can say with absolute certainty that individually they share info and sometimes ski on each others' protos. When the final protos are built and by the time the first production run hits the major manufacturers may have had 25 - 35+ very talented skiers on those skis. This is not static process limited to our snow season, but involves travel of testers and protos to wherever the snow is, often for 12 months of the year. These are often people who have been doing this for decades, are impeccably skilled at technical skiing, can make any ski do what they want. They will ski the ski in a fashion that is consistent with the movement patterns of the target consumer. Sometimes, a model will be killed or altered (and not always for the best) because price point / expectations do not meet market analysis or management's goals. Note that I say major manufacturers (and I put Stockli into that category due to attention to detail and their development process). Many manufacturers simply don;'t have the resources, or don't have the talent pool, or don't have their development calendar dialed to complete this due diligence.
In 30 years of teaching I've run across a few people who would have benefited from moving a binding, but those are instances that I could count on one hand. It is often the Indian, not the arrow.
But maybe if the Indian were a little closer to the target he'd make the shot.
