>for a definitive answer on how to know if a user's D7000 was sharp.<
Wouldn't the definitive proof of a sharp camera and lens be in the photograph? If it looks sharp, I would believe that the body and lens and photographer performed as hoped. No testing needed. If not sharp, then one would check settings and make corrections unless the body and/or the lens needed adjustments. Based on what you say about yourself you have a thorough knowledge of all the ins and outs of photography but...... Comparing your photo to another's will not be a means to an end unless all people are in the same controlled environment with all equipment set the same; maybe with just one person doing the actual shooting. As it is difficult for me, and perhaps some others, to really understand your dilemma, wouldn't it be best for you to start your own program to determine how to tell if a camera is sharp? I say this with no hostility. Good luck in your quest.
Nobody should seek his own good, but the good of others. <><
