The seminal measure of ~319.8 inches or ~26.65 feet, which the architects employed multiple times in the heart of the Great Pyramid, is not a cubit measure, per se. It is instead the average annual amount that the Sun's Tropic shifted at the so-called First Time in 3976 BC; the retro-calculated Year Zero of the Egyptian Civil calendar.

The year of the animation of the first Sothic Cycle, which the Khufu structure was built to monumentalize the 1424-year Sidereal completion of: in inch-perfect accord with the shifting position and increasing length of the 'Stride of Re' – the increasing terrestrial groundspeed at which the line of the Tropic traveled.

Between 3976 BC and 2552 BC (the sole year the Tropic of Cancer lay at 23.97916 degrees N, precisely 6 degrees of latitude below the lat. center of the Khufu) the 'Stride of Re' had increased from ~26.65 feet to ~34.35 feet per year, and hence, the reason for the length of the King's Chamber.

The so-called Royal Cubit derived from a twentieth part of this 'Stride', hence the cubit length employed in the Khufu was ~20.6123 inches. (This is probably most-accurately calculable from Cole's survey, which stipulated 9069.4" as the average base-length of the structure, which, in turn, derived from 22 average 'Strides of Re'.
Thus: 9069.4" / 22 = 412.245454" / 20 = 20.61227".

Hence, the employ of this ~26.65-feet measure (also the lengths of the 43 granite beams of the so-called Relieving Chambers?) is a most profound architectural expression of the ancient Egyptians' worship of their 'Creation'. And, theoretically, since a twentieth part of 319.8" = 15.99", this 'would' have been the cubit length at the outset of the Sothic Cycle, a measure perhaps related by the breadth of the 'leaf' in the Antechamber.

Also note the slight discrepancy to the fundamental measure of the 'Stride of Re' in the year of Egyptian Creation, since a degree of latitude at the Tropic, then at 24.1 degrees N (363,380 feet) is less than at Heliopolis at 30.1 degrees N or at Giza (363,688 feet). And thus perhaps a reason for the slightly uneven Great Step and the uneven north wall of the Antechamber?

I did not have that insight to check the exact 'squareness' of the step in the QC passage when I used digital laser devices, etc. to measure the interiors of the Giza Pyramids. Regardless, the architects reiterated this sacrosanct ~319.8" measure by forming the cubit-high step at that distance from the lat. center of the QC.

However, the so-called Niche, which, as with the statue of the Sphinx, represents the union of the Sun and Sirius (for reasons I have elsewhere explained at length) was offset at the lowest lap by ~6.1" from lat. center of the QC.

Again, this is a most profound architectural expression of ancient Egyptian Creation – and, fair warning, Christians – since the Creation of Atum, from the position of the Tropic at N.Elephantine Island in 3976 BC to the day of the heliacal rising of Sirius at Heliopolis, took 7 days to complete in accord with the first appearances of Sirius over the length of ancient Upper Egypt – thus the offset, since the center to the Eye of Re traveled by (319.8 / 365.25 x 7 =) ~6.13" during the 7 days of the Creation of Egypt preceding the beginning of Calendrical Time at Heliopolis on the first I Akhet 1, on July 17th, 3976 BC, proleptic Julian. (Measure Motion & Maat, pgs. 58 - 74)

Hence the reason for the ~6.1" heights of the so-called 'grooves' in the GG. And, since the latitudinal length of the roofline of the GG (at 80 cubits, at 4x the length of the King's Chamber) relates the shift to the center of the Eye of Horus over a Sothic quadrennium only at that time (2556–2552 BC), the 'grooves', which thus extends just over 24" (8 corbels of ~3" plus the fractional lean-outs noted by Petrie) to all but exactly specify that the 'specific Stride of Re' (the one ten-thousandth part of latitudinal degree at Giza) at 436.4256" exceeded the 'average Stride of Re' at 412.2455" by about 24.18" then, and only at that time. The 'grooves' are a cubit x Pi apart, as the height of the Niche is 10 Pi the height of the Khufu structure.
