Ev has some good advice on figuring out if the APRS power level
suggestion is accurate.

I'll comment on the "eliminate the possibility of other 2m
operations".  That is wildly exaggerated if not quite completely
wrong.  I'll admit I've primarily operated Kenwood APRS radios that
integrate quite well with concurrent voice operations.  Even without
that level of integration, the worst case is that your APRS rig will
desense your voice rig for ~1s every time it transmits.  I don't think
that is particularly significant.  Conversely your voice rig will
prevent reception of APRS while you're transmitting.
