I have followed up on much of the work of JW and your article could benefit from understanding how Jim's Fibonacci Pi of 3.141818181r works with the imperial system.
It translates base 11 to base 12 very deliberately and was known to the AE.
5280 x 3.141818181r = 16588.8 / 8 = 2073.6
5280 / 8 = 660 being 10 chains
so 10 chains x 3.1418181r = 2073.6 This is Michell's cubit x 100.
this base switch from 11 to 12 is illustrated in great detail with metrological significance.
i have written a book about how pi was used to switch number bases by the ancients in my 'stonehenge' series.
It is worth a look.
I have been working with Harry Sivertsen because he has the Stonehenge metrology nailed down.
One of the numerical progressions that explain the SH layout is this one.
diameter as 1 x 1.25 x 2.5 x 176/175 = 22/7
This is one of Harry's suggested diameters 288 imperial feet and look at the spread
288 x 1.25 = 360 x 2.5 = 900 x 176/175 = 905.1429 ( this is whole number when x 7 = 6336)
Now base 12 is the diameter initially producing 360 (no explanation required) then taken to base 3x3 then taken to the imperial /7.
What is really important here is 1.25 x 2.5 = 3.125 and that Professor Thom identified this at Stonehenge because it produces units of 2.5 in the perimeters.
He was correct. 3.125 x 176/175 = 22/7
This is an explanation as to why the 176/175 was being used.
Reading your article it is very apparent the imperial system is being used and this was my original finding when I audited Thom's outputs in his first book.
There is a duality to Thom's measure 6.8 feet being his megalithic rod. It is 2.5 megalithic yards and his megalithic yard is expressed in imperial feet to give the 2.5 relationship. but it ban also be expressed in megalithic units where 0.816 inches represents one unit so 2.72 represents 40 and 6.8 represents 100.
It is this duality of measure that suggested to me it is impossible for Thom to be wrong.
Thon's system is the imperial x 34/33.
So you can start to see how everything is starting to hang together and of course Thom's measures are identified by Berriman but it was before Thom had discovered the megalithic yard.
Our archaeos had better start sweating.
