How did you arrive at £4.40? I reckon £5.10 is the correct price for a
Goodmayes - U1234 ticket.

£4.40 is the price listed in the National Fares Manual.

That's odd - I don't have the printed NFM (and therefore the main
fares tables), but the text in Section L says that the fare for this
ticket is determined by Table 2 on page L4, which says £5.10.
