For the past 15 years the Scottish Household Survey's travel diary has been collecting information on the start and end times and points of journeys all over Scotland. It would be relatively straightforward to select those that were cyclable and map those against the sorts of facilities you mention and assess 'potential'. Those areas with apparently high levels of potential could then be shown to the relevant agencies who could then assess, on the ground, what the barriers were and what needed to be done to realise that potential.
Again, not conceptually difficult to do and I think what CS is doing here is taking on the job of doing what has been, until now, left to individual local authorities.
