Though some of it seems a little contradictory ...
The guidance is clear that Private pilots should not be flying for sport or leisure.
In respect of ratings expiring, our view is that you should be able to fly for the minimum flight time, including instructional flights, needed to revalidate or renew your ratings. For example, if you have extended your SEP rating under ORS4 1416 or ORS4 1418 you should work out the minimum number of PIC hours, landings and instructional flights to revalidate or renew required.
