[aprssig] path analysis for aircraft tracker

Yesterday I took my TT on a short flight around the Annapolis area. I
had my TT hooked up to an Icom HT with a rubber-duck suction cupped to
the window. I was set to transmit every 90 seconds with alternating
paths of WIDE1-1 and WIDE2-2. I was up about 25 minutes, so about 16 or
17 transmissions were made. 6 seem to have made it to Findu, which
isn't bad for blind transmissions. If I am reading the raw data
correctly, only one packet was relayed and every other one made it
straight to the igate. Is this right?
Thanks!
