The actual mean measure of the base dimension; 9069.27 inches per side is confirmed by the field work of Petrie 9068.8" (1883), Cole 9069.45" (1935) and Dash/Paulson 9069.42" (2015). Using Petrie's weighted mean of 20.62 inches per Royal Cubit the square base of the pyramid was intended to be 439.828 rc... 439 rc + 1/2 + 1/4 + 1/15 or 439 rc + 5 palms + 3 fingers

439.828 rc divided by 140 rc (half the height of the pyramid) = 3.1416 rc ... 3 rc + 1 palm

Theoretically if encoding pi was intended then we might have a benbenet (capstone) of 2 rc high (41.24") with a square base of 3.1416 rc. Working from the top down;

pyramid height 5776" - 41.24" = 5734.76"

5734.76" - 5451.8" (top of 203 course) = 282.96"

Here we need to remember the finished height dimension of the pyramid is not related to core masonry course level widths, it should be understood that the core masonry was below and supporting the pyramid casing so the face of the benbenet would align (be flush) with the pyramid casing, so there's no true way to determine if the course thickness remained constant at 22" - leveling at that hight would be far more accurate using blocks half the size or less. Given the latter I would estimate 15 or more courses of core masonry atop the existing 203 course would be in the range.
