ATOC starts journey from wrong place?

This from Captain Deltic...

I note that ATOC's Michael Roberts has a letter published in the Pink 'Un today, in which he says:

Your article “Network Rail lays out £37bn spending plans” (January 9) states that the “average rail fare has risen 40 per cent in the past decade”.

Rather than taking an average of all the prices that were advertised, looking at tickets people actually purchased reveals that between 2001-02 and 2011-12, the average price paid by passengers for a single journey expressed at 2011-12 prices fell by 1.9 per cent, hovering round £5 through that period. That is down to train companies working to attract passengers by offering a range of good value fares, including cheap advance tickets and Railcard deals.
 
So, the average cost of a journey between 2001-02 and 2011-12 'hovered around £5'.

Yet another case of Year Zero statistical legerdemain.

In 1991-92, with the recession biting the average fare, at 2011-12 prices, was er... £4.30.

And while passenger journeys have increased by just over 80% over the same period, subsidy per journey is still 50% more than in 1991-92!

Proof positive of the triumph of privatisation?
