I laugh out loud when I hear [obviously] amateur owners of the D800 say that the left/right AF sensors are absolutely essential because you don't always focus on something in the center of the frame. I guess my "focus and recompose" technique that I have been using since my N90 days must be a flawed technique even though it has resulted in my images being tack sharp for the last 8 years.

Actually, technically speaking, it IS a flawed technique. Depending on the scene you are capturing recomposing will change the sensor plane orientation relative to the subject. I'm not saying that it matters all the time. Most of the time it's fine. But don't assume that there is no flaw in this technique.

You can see the problem of this flawed technique regularly in close up shots. Also I believe you argument misses the point that with a camera of the price of the D800 all outer af points should be equally good and not the left side worse than the right side. It is absolutely legitimate to tey to find out whether this is a real issue or not. To say, just use the center point, is trying to play down an issue that might be a real issue for quite a few photographers.
