<I can gives one more Cloister unit because it is fundamental to understanding the work of Anne Macaulay in her book 'Megalithic Measures and Rhythm's'
The unit is 0.971428571 looks a bit dodgy but if you are in this up to the neck you will know it is a version of pi at 22/7 . If Pi as 22/7 is in weeks then one day is 1/7 and this unit divides into the 0.971428571 unit 6.8 times. Thom.
The unit has a name in Macualay's book - the Roman foot. Multiply it by 7 and get 6.8 units. Thom.>
Wot fun but got to run,
