Pegs measure as follows for the five samples:
(Peg #, X, Y)
1, 6.18, 6.17
2, 6.15, 6.20
3, 6.21, 6.20
4, 6.21, 6.17
5, 6.23, 6.19
(No record of which way round they were printed, so ascribing X & Y is random)
So I reckon that's pretty consistent, and certainly good enough for stuff I'm likely to be making
