Got some more details?  Like:
   what version gpsd,
   gpsd binary from where,
   what hardware are you running on
   what command line to start gpsd,
   serial or USB connection,
   how are you measuring "arrival"

What you describe is not normal.

I would certainly not trust "telnet".  So many flavors that behave
differently.

See if "gpspipe -w" or cgps works better.  UNIX buffering can be
anywhere and everywhere.  They weill never be evenly spaced, the M10S is
not smart enough to do that.
