It's maybe less interesting than it first appears. It's posted by a channel called Lazy Cowboy whose entire reason for being seems to be to debunk the PGF. Take a look at some of his other videos. He's basically the anti-ThinkerThunker, where he attempts to pour scorn on TT's findings by - ironically I assume - using the same flawed methods. He tries to prove that upper arm proportions can be made bigger with football shoulder pads by drawing massive dots on the joints and connecting with lines. It's all pretty dumb.
I need to watch this a few times, but there is an air of respectability about this which tries to disguise the sweeping conclusions they are jumping to - it's quite unnerving. They toss in buzzwords like Lidar, but there seems no scientifically calibrated way this was interpreted, used and adapted. It's all a bit smoke and mirrors.
I posted in a different thread how I think their height is wrong. How they think they deduce it was a smooth sandy surface without obstructions nearly 60 years ago, based mostly on a single photo from years later escapes me.
I'll do a proper review in due course, but I'm not fooled by the veneer.
