In the fare guide, it doesn’t distinguish 7-7, 8-8, and 7-8, 8-9. The single zone journeys in 7 or 8 are charged differently to two zone journeys 6-7, 7-8 and 8-9.
I’ve just started looking at the scope of this and thankfully the fares quoted are those for 7-8 and 8-9 which are the more expensive ones. I’ll need to add a new row at some point in the near future.
And it’s now been corrected. 7-8 and 8-9 have always been the same as 6-7 so I altered the header to reflect that and removed them from the header of the last but one line. The fares have been re-loaded for the last two years for the single zone row.
