Part of the problem is the impression which is given that the Oyster
capping system means you'll never pay more than the total of all the
individual elements bought separately as efficiently as possible.

However, that isn't the case (see the Z5 example I quoted yesterday).


That's an assertion of what is charged, not an example. Evidence would
be a Oyster Journey history showing the amount charged and/ or repeated
refunds and/or a ruling by the ASA that the "never pay more" is
misleading advertising or a FoI disclosure agreeing that.
