This is a summary of my own mathematical analysis of the Heironimus-Morris recreation and my conclusion that it is not a valid recreation of the Patterson-Gimlin film.
Some frames of the Heironimus-Morris recreation were posted to this forum last month, in the thread called "New Article by Kal K Korff". I decided that a quantitative analysis of the recreation would be useful.
To that end, I used one of the frames of the Heironimus-Morris recreation to perform some calculations for the body segment dimensions. Given Heironimus' height of 72.25 in. (Long 2004), I proceeded to calculate the length of the legs of the recreated film subject: 39.7 in.
The leg length to height ratio for the recreated film subject, then, is 0.548H. This is only 0.77 standard deviations from the human mean (0.530H), which is the 55.9 percentile, present in one out of every 2.27 people. Note that this is well within the range of a human being.
In contrast, the ratio of leg length to height in the subject of the Patterson-Gimlin film is 0.460H (Glickman 1998). The difference in the ratios indicates that the subject of the Patterson-Gilmin film and the recreated film subject in the Heironimus-Morris recreation are not the same entity.
Thus we can conclude that the Heironimus-Morris recreation is not a satisfactory recreation of the Patterson-Gimlin film. The inability of Heironimus and Morris to successfully recreate the Patterson-Gimlin film with the a costume and materials similar to what they allegedly used to hoax the original film strongly suggests that Heironimus and Morris are not being truthful.
