I wish it were true...then it would fit perfectly into the base width of G3 (aprox 4150").

This doesn't add at all.

Petrie's data (section 37) states the beginning of the horizontal at 0" above end of entrance passage floor. Unless....he didn't realize that debris covered the small step at the start of the H.P. that you mention.

Not really...we don't know where Petrie set his station to measure the total angular length from the base of the passage. Was it on the horizontal section, the entrance section or with reference to the E.P. ceiling ?

Why 1,174"?

Best.
