The worked example here suggests 1.57x10^6 m/s as the Fermi

to know offhand whether that's reasonable, and I'm too busy to
refresh my understanding at present:

That value is still two orders of magnitude slower than the
speed of light [snip]

Of course, but that seemed rather too obvious to be worth pointing out.
