The discount is really dependent upon what ODTC you would have bought
otherwise - i.e. how many zones. Below are the current (2006) off-peak
ODTC prices, along with the saving possible if one buys a
railcard-discounted ODTC at the price of £4.80.

Zones 1&2 - £4.90 (10p cheaper with railcard)
Zones 1-4 - £5.40 (60p cheaper with railcard)
Zones 1-6 - £6.30 (£1.50 cheaper with railcard)

Zones 2-6 - £4.30 (50p more expensive than railcard discounted ODTC)

Even when compared to a full price all zones ODTC you still don't get
the normal 1/3 discount, nor do I think this has ever been the case.

Also, if you buy the railcard discounted ODTC from a Tube ticket
office, you actually get a Zones 1-D Travelcard (normally £7.40),
saving £2.60 (pretty much a 1/3 discount).

(If you buy it from an NR ticket office or machine, you just get a
plain old Z1-6.)
