Hi Mj ...
I am surprised Wayne did not comment on or take note of this ...
... then the vertical heights of all four shafts is very close (within an inch or so) to the equivalent of 70 royal cubits (as 20.632"/524mms), which could be seen as one-quarter of the Pyramid's intended height.
Even in 3-dimensions it seems to involve quarters ... although I still like 20.618" for the length of a cubit ...
