I refuse to believe the P4 guys can measure accurately and consistently to 2 decimal places of a millimetre!
As one of the P4 guys that is a member of the EMGS, I can assure you that it is just as easy to set a pair of wheels to 17.87mm as it is to 16.50mm.
It’s simply that for some reason EM modellers tend not to quote the second decimal place as though it doesn’t exist. Like global warming, it’s still there, whether you believe in it or not…
My BTB gauge has been measured to the average of three micrometers and marked accordingly. Of course it will never be 100% accurate to that measurement, but that is where the ability to build to a consistent standard is more relevant that being able to build to a spuriously accurate one.
