Thanks Paul - it will indeed be on a paper ticket because will have been

I agree that it's not ideal. It seems ridiculous to have to change
trains because the ticketing system is so intractable.

If you're starting from a station inside the Travelcard Area, you can
get an Amersham to Zones 1-6 Travelcard for £11.60, which is NR's
workaround to deal with Zones 7-9.
