I'm still studying this and don't really understand it all but I have a few observations.

First I'm struck by the low density region above the east side. At the base of the pyramid and exterior the low density region is largely on the north but above 70' (deeper than 20' from surface) the low density is much more profoundly to the east. I'm still digesting the implications of this. Perhaps the Mafdet Lynx does not lie on a straight line as does the Sphinx.

The purpose of the void does not seem apparent to me at this time but, perhaps, it suggests a connection between the niche on the NE corner and the second Sphinx under the NE corner.

The timing here seems really "funny". We're nearly two years overdue for the thermal imaging results which was completed long ago and then last week Hawass released his big new book. Now this is released, purportedly without approval, and the team is sure to be kicked of the plateau just when people will start screaming for muon imaging behind the thermal anomaly. I guess it's very convenient if you're as afraid of the pyramid and its secrets as those calling the shots.
