well, 72 degrees 00.000' would be identical in either format, where
71degrees 59.500' would be a long long way off between the two. one
measures with a 100 point scale, the other with a 60 second scale. You
could be as far as 40% of a degree off in either direction. that could put
you in another state.

My knowledge of the data is not 100%, but then again, I'm a lowly artist.

Out of curiosity (and being too lazy to dig on my own), how far apart are
they, relationally speaking (inches, feet, miles) or is this question way
off course? Is there a standard difference?
