But it does show the complete nonsense of it, because surely the issue
is not which train you travel in, but whether you are potentially
travelling to an unbarriered NR station without needing to pass
through any barrier till the destination?

The issue *is* which train you travel in, because TfL are prepared to
take the revenue risk that you might not touch out, and the TOCs
aren't.

Oyster charges between points, not according to which train you sit
in, which can't be known.

The reason for OEPs is supposed to be the number of unbarriered NR
stations that will be part of the scheme. The revenue is distributed
according to where PAYG starts and finishes, surely? If I touch in at
Oxford Circus and out at Harrow & Wealdstone, the revenue isn't
distributed differently if I change at Wembley Central to LM.
