There is nothing in any publication I have seen that refers to reporting at waypoints in a CTAF, all reports for traffic advice should be at distances (and bearing/quadrant) and not at obscure waypoints from an approach chart.
Is it just me or has the overall standard of radio procedures dropped off.
Basic stuff such as departure reports in CTA and taxi calls OCTA.
Maybe its just the new right hand seat "where does it say that" brigade that are passing through regionals.
