Ferries Plan Contract Variations and Timetable Changes: FOI release

In relation to the above and in particular the following question and answer:

"The detailed explanation and the associated financial impact thereof which therefore illustrates the increase in subsidy level from £868m to £975m?

The original Bid Subsidy for the Contract was £868m. The increase to £975m includes the following approved contract variations: Summer 2016 & Winter 2016/17 Timetables £68.4m."

I have spent the last couple of days comparing the summer 2015 and winter 2015/16 timetables to the summer 2016 and winter 2016/17 timetables and finding it very difficult to identify changes that would explain an overall cost of £68.4m or an annual increase of £8.55m over the contract period. Could you now please provide, under FOI legislation, a breakdown of the timetable changes by route and cost? Comparing summer 2015 and winter 2015/16 to summer 2016 and winter 2016/17 timetables, identify changes explaining overall cost of £68.4m or an annual increase of £8.55m over contract period. Provide a breakdown of the timetable changes by route and cost.
