I made many LU journeys in Z1-4 and one costing 1.40 to Z5.
I was charged 14.40, rather than 12.00 - the Z1-4 cap + 1.40.

....

Zone 1-4 + an extra single journey is how I assumed the worked too, but I'm
apparently mistaken. Does TfL explain exactly how it works anywhere?

This page, http://www.tfl.gov.uk/tickets/14837.aspx , states

"Oyster will work out the cheapest combination of fares for all your
journeys in one day."

A zone 1-4 travelcard plus a single oyster fare would have been the
cheapest alternative.

The Z1-4 cap is £10.60, plus £1.40 is £12.00

But the Z1-5 cap is £15.80 - so how does £14.40 arise? (Other than being
£15.80 minus £1.40, which makes no sense).
