If you have User -> PRMD -> ADMD -> ADMD -> PRMD -> User (1) (2) (3) (4) (5) the time is measured from (2) to (4). The PTTs care only about what they can be held responsible for, and will write off responsibility for anything they can get away with. In this case, they have said that they only want to care about delay that occurs within their club, and not within the "untrustworthy" PRMDs. Whether they in fact follow their own definition or not, is another thing entirely.
