Whoops. Missed the point you were making.
Note that W0NED-10 is not necessarily the fastest I-gate in the area, so it is possible that the later I-gate actually got your packets to the Internet more quickly than W0NED-10 did (if W0NED-10 submitted them to APRS-IS at all). Hence, aprs.fi would not see any report of W0NED-10 that they had heard your station because it was duplicate-discarded.
It's been said hundreds of times before by dozens of people, but I'm going to say it again:
You CANNOT use aprs.fi (or the APRS-IS backbone in general) for propagation analysis, because it only keeps the first network-received copy of any transmitted packet, not all of the later copies injected by other I-gates, such that you cannot see all RF paths a packet took to get to the APRS-IS.

I transmitted an aprs position packet from my aprsdroid unit.
After doing so, my aprsdroid unit (KD0PYK-7) was properly positioned on the APRS.fi map.
Looking at the 'Last path' for my aprsdroid packet, it shows KD0PYK-7>APDR16 via W)NED-10....
This is appropriate.

However, when I look at the info display for W0NED-10, I don't see KD0PYK-7 under 'Stations heard directly by W0NED-10'.
Why not ?
