Joe,
These are first generation data recovery , he plot shows the bit recovery pattern , in a yes/no format decided by the s/n threshold its possible to recover the amplitude of each bit as well , but that's not embodied at the moment
Yes for 100% decode , then the Fade=% , s/n is the average along the time line 

73-G,

Thanks for this Joe.
  Are these graphs showing reception vs time? The signal levels and
fading seem inversely related.
