You are making rather emphatic statements about how APRS works, based on the
assumption that P=.5 . My question is: how accurate is that assumption?
Has there been any network analysis, or any mathematical analysis (perhaps
based on or related to the APRS Aloha circle formula) to verify or support
I'm not arguing that it's wrong - intuitively, it sounds about right to me -
but assumptions should be backed up, when design choices or operating
methods are based on that assumption.
