No, it addresses the failure of a VOR and the failure of a GPS satellite.

No, it doesn't =address= this, it =uses= this to =address= the original
point.

you're now comparing the failure of about 0.1 to 2% of the
VOR system to the failure of about 69% of the GPS constellation.

.... which is my point. A single VOR failure brings down 0.1% to 2% of
the VOR system. A single failure brings down 69% of the GPS system.
(your numbers - I don't believe the 69% part and haven't verified the
0.1% to 2% part though that sounds reasonable)
