Jim Wakefield's GP is designed against base 99
31104/9900 = 3.14181818r Fibonacci pi, ask Jim about this as well.
Mine and Hugh's GP is designed against base 100 - see cubit theory and its duality 100/4.8 and 99/4.8
I think the theoretical design was cut down for build time reasons and that is what Petrie hit as the base length
