I estimated the POI/BG height and placed him in this approximate location first considering there were 2 white spots on the side rail. That position would have placed Libby on either the last platform or slightly off the bridge. If Abby had been taken the shot from the platform, I would have expected the image to be less pixelated. But then I am not familiar to how good or bad of a quality her cell phone (what kind?) video would be. Then GH published his video of the first suggested location ( he corrected the location afterwards and published a new video).
I went back to Abby's picture on the bridge and measured the width of the bridge walkway based on Abby's known height (ISP poster) of 5'4":
I considered GH's video and measured the height of the POI/BG based on the above measurements, which got me to about 5'9" to 6' allowing for +/- 2inches of faulty readings (Abby's hair). Trying to re-establish a vanishing point in the ISP image and visually trying to fit the POI/BG in on the bridge utilizing the same video of the bridge as GH also let to approximately the same result while leaning towards the shorter end of the previous measurement of 5'9" to possibly only 5'7".
Then GH corrected the POI/BG position and placed him close to being in the vicinity of the last platform, which would place Libby definitely off the bridge and possibly on the part of the land, that is a bit higher than the bridge itself IMO. Well, considering that new location from GH's video and trying to measure I am off by at least a foot. So, either Libby had an optical zoom on her cell phone camera and that may contribute to the discrepancy, but then why am I in agreement with the first reading and the optical fit-in re-scaling method as opposed to the second reading?
It is therefore possible, that the POI/BG has a height of either 5'7" or even less than that. However, considering that the side rails RRTs are 4 inches tall ( a member went out and measured them) and that the width of the walkway is between 78" and 80" and that the visual re-scaling and actual measuring all put him at about the above measurements, I am tending to say, that GH's final positioning of the POI/BG may be correct, but that a possible optical zoom (not digital) makes it more difficult to establish final height.
Why LE has not published an approximate height and weight estimation is beyond me. They could have remeasured and recreated based on Libby's phone/zoom ( if applicable) and we could have excluded a vast majority of suspects.
All IMO

I snipped off the images when quoting your post for brevity, not that I didn't enjoy them
I was glad to read your analysis, because I agree completely. I keep going back and forth as to whether or not Libby was actually on one of the platforms, because I get a better match between ISP images and my mockup in a 3D reconstruction if I place Libby a little higher than the bridge and a little further back (i.e. to the side of the bridge up the hill a little). My best guess at BG height based on these unknowns is 5' 8" +/- 3" because there are so many unknowns. I also agree w/ Gray Hughes estimate of BG location on the bridge
