It seems to me that you're quite lax about your radio calls as are a lot of other pilots, I for one am not.
planemad_bk, It seems that you are not as on top of your game as you think you are. Have a read of what the differant symbols mean.
Some things are not required to be read back twice. For example.
A flight plan has been submitted with A/C type, Rego, callsign, and flight rules. So you do not have to repeat these in a taxi call.
Same as transponder code and destination. They have been received and read back during obtaining an airways clearance.
Your position on the field has been determined during a request to push back, so this no longer needs to be transmitted.
So all that is left is POB (excluded for RPT and probably only for commercial privacy reasons, I dont really know), and whether or not you have received an up to date ATIS (and of coarse the actual request to taxi).
if there is an exemption for RPT aircraft to not transmit the full taxi call at a controlled aerodrome?
In short, NO. But there are no requirements to do so either.
