Gday GG-
Forgot to mention- Ralph has been known to develop violent tendencies towards backseat drivers in his own profession, and knows exactly how annoying it can be! Hence he avoided making his PPL background known to the charter pilot, since he doesn't know him personally, and doesn't want the guy to feel like he's being watched like a hawk.
Ralph is keenly aware of watching another colleague with a PPL do exactly what you are talking about on another charter with another operator some time ago-and Ralph was really embarrassed to be thought guilty by association
