SC: I am paraphrasing Lehner:
"The straight-on ramp against one face of the pyramid has had strong advocates... it left the four corners free for backsighting, still considered by some to have been important for maintaining control of the pyramid slope." Dr Mark Lehner, TCP, p.215
SC: Afraid youll just have to ask Lehner who he had in mind.
