I can try that as well, but it really does seem like this is the full
list of what you can get (notice PMTKCHN has room for up to 32 sats!)
What I have found though, by trial & error, is that my board can run at
a little over 3 Hz:
I can ask for any update interval from 307 ms and up, so 333 ms is fine.
When I ask for 200 ms (5Hz) I get a '2' response, i.e. command was OK
but could not be executed.
