yes opps a daisy!!
it should be 356.4 and is on the last page of the model but you are looking at a cubit of 20.625 and that is produced by 363 solar days and this number is a real beaut. the difference 363 - 356.4 = 6.6 and that is the chain or 13.2/2.
33 x 11 and it is possibly in the analysis of the Knowth tablet by Robin Heath. I will find it somewhere but it may take a while.
anyway it is 99/4 x 14.666r
I will attach the model for 363 in a bit. It is all good fun.
Variable Cubit Calculation
Speculating that number 25 is naturally embedded in the cubit.
363 A Input solar days
7 B divide by 7
51.857143 C to give weeks as 16.5 22/7 Pi units
2904 D multiply by 56 to give 8 weeks in days 56 Postholes
The Megalithic Yard and Saxon Yard
6171 F-D 2268.75 In Thom's megalithic yards
6171 F-D 1870 in Saxon Yards 1851.3
3.125 GP to Stonehege Ratio (Fixed)
363 E Input solar days
9075 F multiply by 25 so all 4 sides equate to 100 by 25 to agree
20.625 G Divide by 440 to give the variable cubit 0.825
Projected Height of the GP
5775 using the Sekhed 231
5777.398481 Using a Pi pyramid design
5778.086889 Using the modern metre
5778.820708 Using the ancient metre
