The One Day Travelcard does not go back and recalculate all the
journeys and then refund you money if your original purchase decision
somehow doesn't end up being as good value for money as you thought it
would. Quite why people think capping works in this retrospective
manner I know not.

Because Oyster is supposed to be clever, and they promised "Oyster will
work out the cheapest combination of fares for all your journeys in one
day."

If that's a Z2 cap plus a single to Z4, rather than a Z4 cap, surely
it's not beyond the wit of their computers to charge what they promised?
