It doesn't change the fact that circularity was a feature of early and bigger monuments and the later smaller monuments despite being esier to set up were no more circular and very often deviated from the true circle .
That just doesn't work down here George although it may work elsewhere. Bodmin's large early circles of Stannon, Lowden and Fernacre are nowhere near circular and have definite straight sections compared to all the later smaller ones that haven't.
