Dash, Cole and Petrie are in agreement that the average base-length of the Khufu is 9069.4". At 440 cubits that is 22x the length of the KC.
I.e., the Khufu was built to the measure of 22 average Strides of Re in 2541 BC.

The distance from the doorway to the W. wall of the Khafre Main Chamber is 412.8". At (412.8" / 20) 20.64" cubit x 20.5 average Strides (410 cubits) this encodes the base-length of the Khafre as 8462.4". Which is confirmed by the Tropic's ground-speed in 2519 BC, at 412.8" / 34.4 f.p.y. (Pg. 256)
It is the reason why the coffer in the Khafre Chamber was blocked into position, since the cubit computation derives from the Tropic^6' position there in 2519 BC. The Khafre Main Chamber was designed to 9.5 cubits in width, the Pyramid's height is 274.5 cubits. At 20.5 Strides base-length it measures half a Stride less than the Red Pyramid base, and a Stride and a half less than the Khufu base. The Pyramid's offset between average and specific Strides was 40 days, half that of the Khufu Pyramid. The general design scheme of Giza was whole numbers for the Khufu, half such for the Khafre, and quadripartite for the Menkaure. (pg.187)

Petrie did not measure the casing of the Khafre since it was inaccessible in his time. He measured the rock ledge around the Pyramid at 8474.9" average length. If that were the base-length of the Khafre, then, at 410 cubits the Tropic's speed would have measured 413.41" per year, which it did not until 2495 BC. Neither could the Khafre have been built to 411 cubits in base-length, since the Tropic's speed would have had to equal 412.4", which was only so in 2535 BC, during the reign of Djedefre. Also, every Pyramid in Egypt designed by the average Stride was built by full or half Strides, as for the length and width of the KC of the Khufu.

These values are highly specific and not a matter of estimation, as Lehner's figures are. In this case, both Lehner and Petrie's figures are inaccurate for the base-length of the Khafre. See pg. 228 re. how the Heliopolitan architects interwove the base-length designs of the Meidum, Dashur and Giza Pyramids.

I'm happy to discuss, but for goodness' sake man: if interested, read my work thoroughly before you fire off misguided comments or misquote me. You don't even seem to realise there was no year zero between 1 BC and 1 A.D. or that the prototype Pyramids of Meidum and Dashur were not built under the Sun Eye, rather, considerably distant. There were distinct reasons for their locations, (pg.117, 177) but time did not 'run backwards' or from south to north... etc..
