I saw something the other day that referred to a 'Zone G', for fares set by
c2c for some stations that were beyond zone 6. Apparently similar to the
'internal use' Zone W for the fare beyond the zones set by LM, ie Watford
Junction.

As I can't seem to find the document online again can anyone suggest what I
was looking at and confirm I wasn't mistaken - and does this suggest there
may be other PAYG destinations outside the existing zones on other routes
eventually?
