My logic was that £4.50 railcard discounted is £3, or anyway below the
cap. With a railcard from Cambridge you can pay more either way. Make
only two zone one journeys and a Travelcard is more expensive but make
three and using Oyster will be more expensive. Sometimes you just don't
know what to buy because you don't know what tube travel you will make.
Without a railcard Oyster is always cheaper of course. You don;t get
Oyster capping discounts with a Network Card, by the way.
