If going via Gatwick you have a choice between the Gatwick Express,
which is non-stop to London, and the Southern local services, many of
which only stop once or twice between Gatwick and London. The local
trains cost 2/3 of the Gatwick Express fare. ...

Really? What are the current fares? Some years ago it was more like
9/10, not 2/3.
