I did an un-planned set of trips on Wednesday, which quite by chance
emulated the Oyster capping conundrum discussed here recently.

viz: Several trips within Z12, all charged to £2.10 each until I hit the
off-peak cap of £7, and then later in the day a sole Z13 trip.

If I had bought that last trip in isolation it would have cost £3.20
because it was during the evening peak, but because the *cap* doesn't have
an evening peak period I was only charged 70p, via the higher Z13 cap of
£7.70

This lack of triggering a Z123 peak cap, within the journey scenario above,
makes it moot whether the day's travel would be charged at the Z13 peak cap
(£10.60), or the sum of a Z12 offpeak Travelcard (£7.30) + a peak Z23
single (£1.60) - which totals £1.70p less.

I hope that's completely put the conundrum to bed!

I am not sure how making a number of journeys that were all in the off-peak
capping window proves anything.

Had you started with a peak Z23 journey (£1.60), then made several off-peak
Z12 trips, I suspect you would have been charged £10.60 rather than £7.30 +
£1.60.
