Hey Aaron, thanks for the feedback, I actually had some time to think
about this (yay holidays), and I'm starting to agree with you: leaving
the values for the bounds unchanged is probably better. I think I'll
just add a convenience function to simplify conversion, and I'll send
an updated set soon.
