The word Private was in quotes " " to emphasise the comparison to GA.
eg. Private RAA hours = similar to Private GA / PPL hours and ultimately CPL hours.
Was to highlight the fact that in RAA you have 100 hours "Private flying" ie, command hours flying around in circles (which may include obtaining your cert) versus a CPL which as you know is quite obviously different and is a lot more dual than in RAA and with the IR on top of that.
