I sort of assumed that those hops (not highlighted in green) were just not showing any return on the ping at all.
These (addresses 15, 16, 18, 19, 20, 23, 24) are consistently 100% PL thoughout the period of the trace. I kinda thought that these adresses were either unkown or were "unpingable".
address 14 seems to be the BT side of the BT- NY gateway and its showing 0% PL in this trace.
This would then leave address 22 showing an 80% PL and address 26 (main arena) showing a 32% PL.
