> The progression increases to generate values like 66, 660, 5280 7920, all values that form the "11" navigational system with a mile of 5280'.
Flawed premise: the modern mile being 5280' is more or less an historical accident. The Roman mile was 5000 Roman feet.

- thechao 6y agoFor his 3rd measurement he’s claiming a number with 1/1000000ths of an inch accuracy. Which is the same fabrication standard we use in modern CPUs.

- OJFord 6y agoAlso from TFA: > The Romans had a foot of 11.664"*. Their pace measurement was 5 Roman feet or 58.32" (4.86'). Their mile was 5000 Roman feet, which would be equivalent to 4860 ancient or modern English feet. The Roman measurements were divisible by 6. > The ancient English had a foot of 12", a yard of 3', a fathom that was originally 5.5', a rod or perch that was 16.5' (3 fathoms), a chain of 66', a furlong or furrowlong that was 660', a mile of 5280' and a league that was 16500' (3.125 miles). The English overland measurements were divisible by the number 11, as were the ancient Scottish measurements, with their mile of 5940' (1 furlong greater than the English mile).
