The APRS rule of thumb is that the range of mobile packet is at least half or less than voice.  Reason is simple.  Ears can ignore a millisecond of flutter, packets cannot.

That is why the standard for PHG range circles displayed on APRS maps were cut in half back around 1998 or so when substantial experience proved this.
