Meanwhile those of us deciding whether or not to buy outboundary
travelcards have a complex matrix of decisions based on how much out
particular TOC marks up (or discounts) the price when added to a London
Terminals Ticket, and how that all shifts around when buying off-peak,
or with a railcard discount, and also attempting to predict whether one
will hit any of the caps is travelling ad-hoc.

If they can stick *all* of that into the contactless system and
guarantee to offer the best deal from the numerous potential
combinations, that would be great. But how the ordinary traveller is
supposed to audit that, I have no idea.

Ha, well I can't really see the above happening!

Very similar issues can easily result from ITSO cards making non-optimal
(for the passenger) choices about which tickets to use *today* when you
have various period returns 'in stock'.
