Indeed, Tim.
It's not even as if one could assume that there is a core list of airfields (as listed by Wynn) that were officially V-Force dispersals, with others that happened to be able to host them.
That list of his is wrong from top to bottom - omitting Marham from the Class Ones, giving too few four aircraft dispersal airfields, and missing others entirely, while including some (Stansted, for example, and perhaps Bruntingthorpe) which don't seem to have been used at all.
