Let me put it another way. You made available 6 NEF files. In at least 5 of the 6, your subject of interest is obviously moving, and you shot these at a shutter speed very susceptible to subject motion

In the 6th image (701_1009), focus was not where it should have been- the subject's face.

None of the images are razor sharp anywhere. You did a credible job (with one exception) under the circumstances but I don't think it's "good enough" for these purposes, simply due to the circumstances and challenges of that venue.

That is NOT an assessment of your skills. It is simply a statement that this is not a good set of images for the purpose of supporting your claims.

I don't think you got the point I tried to make about "extraordinary claims" and "extraordinary evidence". If you want to find agreement with your claims, you need to eliminate all doubt on our part, and you cannot expect others, via forum discussions, to thread fine needles while assessing a problem like this. You need slam-dunk impeccable images. That simply cannot be done hand held, in a poorly lit room, of obviously moving subjects, at 1/100s and 80mm.
