For those of you not used to meters per second, 10 m/s = 36 kph = 22.5 mph
15 m/s = 54 kph = 33.75 mph
which would be sufficiently fast to catch just about any of us on the net,
barring any champion sprinters out there.
[Incidentally, I have seen the Farlow et al. manuscript, and highly
recommend it to everyone whenever it actually reaches print.]
