Hi Graham,

I did an analysis using Coles data for G1. I did not adjust the base lengths. After adding the platform widths and applying the triangles I got the following results in cubits:

G2 NE Corner
			x	y
Predicted		0	0
Actual			0.2182	0.078

G2 Quarter-Base
Predicted		102.8301
Actual	North		102.6897
	East		102.7293
	South		102.7498
	West		102.8293
	Average		102.749525
	Deviation	  0.080575
	Percent		  0.08% (8/100ths of one percent)

The solution appears to be very accurate regardless of the data set used.
I think G2 is solved.
