This question is a spinoff of the wonderful work Bill Munns has done, along with Gigantofootecus and Apeman, which prompted me to think, "Are there other images, in picture, or video, format where the site can be revisited and the subject measured accurately?".
We've seen how much Bluff Creek has changed in 40+ years. That hasn't helped video analysis. It would be interesting to find an image, or another video, return to the scene where shot and essentially do what Bill has done with captured images of Patty at Bluff Creek.
If one could return to a site that has not changed much since since the image was captured perhaps height could be determined with precision. Let's say, for illustration purposes, that the subject was found to be 7' tall. That would not prove the subject captured was real but it would geometrically reduce the odds of it being a man in a suit. Those odds could be calculated accurately and everyone could make their own judgment about what the results mean.
