Is it possible that the appliques were exchanged for free simplex accounts and the economic potential/value of the appliques is the potential revenue-generating capacity of the "free' simplex ESN's over their lifetime? This might account for why building additional ground stations has the result of generating more "free" simplex accounts. I am still digesting RW's data but this was an initial hypothesis I had. In that scenario, the economic life of the appliques ends when the free simplex accounts go away. A lot of bartering going on here it seems to me. Also, if I read it right David gets a premium every time a new ground station is built? I am out of my element so I am only asking. Thanks, Mide! IndyJonesOhio.
