I have discovered one anomaly:
WheelCalc utilizes a flange to center measurement.
Pro Wheelbuilder Spoke Length Calculator utilized a flange to locknut measurement.
If I use the same dimension for those two different dimensions, the resulting spolke length is much closer, even though inappropriate.
If I put in the dimensions which the program requests, the spoke lengths are much different.
Time to quadruple check in order to find my (other) error.
I have "learned" more than one thing today (although one of those I already knew).........
