A bit nit-picking here, but I count only TWO digis in the example.  The 
first hears the WIDE2-2 and transmits a WIDE2-1.  The second hears the 
WIDE2-1 and transmits the WIDE2-0 which is more commonly shown as WIDE2 
(lack of a -SSID implies -0).  In addition, the second digi should also 
set the "used" bit in the AX.25 header because it decremented to zero 
which is typically then shown as WIDE2*.
