Please explain how to use this UI-View "decaying Algorithm".  I am using 
UI-View 2.03 as an IGATE and all it has is a fixed rate that I can change 
if I want. Doing this is a royal PITA during an emergency.  I don't see any 
documentation on how I can set it to exponentially decay from an early very 
rapid rate to a much slower one over a defined interval.

The term "decaying algorithm" has a distinct meaning in APRS.  Either 
UI_view has it or it doesn't.  Which is it and if it has it how do we make 
it work?

I have said it before and I will say it again.

Any APRS client that fails to implement the following basic design elements 
of APRS is by definition and in actual use BROKEN.

In my opinion APRS style messaging in UI-View is broken and can not be 
fixed.  Furthermore, I think this precludes UI-view from functioning 
reliably in an emergency.
