Concerning XXI. You've competely lost me !
I am wary about the temple with the 3 entrance at each cardinal point for each house of Israel. Laying this kind of thing on a large map must by chance have loads of alignments because of the number of sites. The bigger the better. There is no accurate long / lat coordinates, no azimuth & no spherical trig calculations. I would not touch it with a barge pole at the moment.
