Oh, I never compared the speed of the two. I should have done that when I
changed from RIEMANN to RADON some time ago. I prefer RADON because (a) it
is the currently supported routine and (b) because I found it had more
functionality.

When benchmarking, of course you should make sure the speed difference
between the two routines isn't just due to more elaborate interpolation by
one of them. Did you check that?
