At Abu Dhabi in the '70's it didn't do to be approaching ahead of a Mirage on its way back home; they were usually on 3-4 minutes left, or less, by the time they got on to finals.
Or so an ADAF pilot told me once over a beer, to explain why I had been told to orbit well away from the approach for 10 minutes when returning VFR from Dubai, late one night, in a friend's Cherokee.
