Dear Bill, LF Group,

Yes, the 63710 should be 67310 - the 32 digit result is courtesy of the
Windows calculator, but fortunately I used the right GRI for that....

When I did the above division on my inexpensive solar-powered calculator,
I got 7.8480615 Hz, not 7.4283167 etc Hz.  Is this another case of can't
see the forest for the trees or should the GRI be 6731 instead of 6371?
I bet you took so much care to make sure you typed in the 32-digit number
correctly you shifted the typo to the other number (2 places!), right?
