What exactly is "focus priority"?

On more advanced bodies like the D7xxx and Dxxx series, you can determine whether the camera should take he shot even without focus having been achieved (shutter priority). When you set it to focus priority, it won't take the shot unless focus is achieved. For testing purposes you want to eliminate the chance of purposefully taking a shot out of focus.

In a tripod setup it really is unnecessary to use focus priority. You can see the green light and continue to shoot as the target and camera no longer move after focus lock and in AF-S focus will not change once locked.

My opinions are my own and not those of DPR or its administration. They carry no 'special' value (except to me and Lacie of course)

I disagree. Not everyone is carefully enough to first press the shutter button half way and wait for focus to lock. Also, if your lens is too close to the target and you are not in focus priority, you will take an out of focus shot. Set things to focus priority and you prevent such mistakes from influencing your test results. It is a test so control the environment so results cannot be questioned and conclusions can be drawn unambiguously.
