I’ve seen a lot of believers claiming very small details can be gleaned from the PGf. The latest I’ve seen is: http://www.isu.edu/rhi/pdf/Munns%20&%20Meldrum%20Commentary_2013.pdf . I find it hard to believe that such details can be reliable gleaned from the footage. Having said that, I know that I’m not an expert, so I’m wondering if there are any scientifically sound studies on just how much/little can be reliably taken from the footage? Or if anyone has a refutation to the points raised in the above article, that would be useful too.
