One thing that could have been done was to invent two different units: one that measured 3 1/7 times the other (rather like the remen and the RC). One set of units - y - could have formed the diameter; and the same number of units - y - could have been used with the larger units to set out the circumference.

However, I don't know of any evidence to this effect.

I am aware of that.

... and there is no evidence that pi was used in the architecture of the GP.
