This makes no sense at all. In general, an ACK has no better or worse chance at delivery than any other packet.  In reality, a bare ACK is short, therefore slightly _more_ likely to be delivered without error.   Again in general, messages are longer than the average APRS packet and therefore _less_ likely to be delivered without error. 

All APRS packets (on RF) are datagrams with no guarantee of delivery.

Bob, I don't disagree with your suggestions for making effective use of APRS messaging, but let's get the facts straight. Why do you claim ACKs are less reliable than messages?
