i believe i have read that article but i have read so many i lose track, i have not logged it. It is a good one in respect of the tropical year.
The starting point at SH is the obvious 365.25 days in a year and this can be reset at SH twice a year at the solstices so even if it is not strictly 365.25 it does not matter because the start of the year will always be the same.The lesser cursus records the summer solstice sunset still to this day so it is an absolutely accurate clock that does not lose time in one year.
Working inside this anticlockwise clock is the Asimov year of 364 days producing a 1.25 day lag every year so every 8 years a 10 day reset is required. The avenue is divided up into eight alignments based on archaeological evidence so they could have done this. 364 x 8 is 2912 and this is 56 x 52 the denominators of the two versions of Pi as 176/56 and 163.2/52.
Perhaps the year end celebration period grew from 1.25 to 10 days in a cyclical build up. This works with the maths.
2922 days in solar years and 2912 in lunar and solar periods always in whole numbers with a 1.25 day period always accurately reset.
176 is the saros sysrtem and 163.2 is Thom's nodal system and every day in this system is absolutely comparable with the same day in the previous year for accurate astronomical prediction.
I think I read this somewhere too but can't find the reference anymore so there isn't one in my book.
This is again the sacred number 10 which makes me suspect that this system is more than a possibility.
This might be of interest
my workings in Peter Hariss's book where i found the meg yard x 99/7 (10 root 2 approx) work together at the Aubrey to give 280 units
