My 70-200 f/2.8 has back focus

I just got a 70-200 f/2.8, and it seems to have back focus. I wrote it up on my blog, with sample pictures and analysis. I'd appreciate any comments on my analysis or conclusions, as well as other tests I might do to eliminate user error as the source of bad focus. (I know my D200's focus points well, for example.)

Here's are two examples -- 100% crops from the center of images where the focus points were the truck and the leaf:

If further tests confirm this, I guess I'll have to send it to Nikon for adjustment. Luckily, there's a Nikon Service Center an hour away, conveniently next to the largest camera store in this part of the country
