I'm only just catching up on the series, and watched the one about
revenue inspectors yesterday. Doing some quick sums on the back of an

inspectors as the fares they are failing to collect (£20m a year).

That seems a reasonable amount to spend. How much more revenue would
they lose if they didn't spend anything on inspectors?
