Never had any issues staying separated there. The RPT's just join a 10 mile final and huff and puff if they haven't made sure every one knows how important they are to be in the rhs of an a320
That is your reality, not theirs. Have you got traffic in by any chance? I doubt they're big noting when they're heading in there. Most of them are decent blokes/girls that want to keep their ATPL until they retire.
