I agree in principle with your statement. However, the other pilot was VFR
and flying a practice ILS to the landing runway. His "final" was about 8
miles in length as he flew the ILS. He was in a Warrior and I was flying a
Baron, so there was a significant difference in speed.

While I easily could have turned in and landed well before him, why make
things tight and more stressful for him at night during a practice approach?
I decided to not force the issue and extended the downwind (a long way,
since he was relatively so slow). It was very clear from the tone of his
voice and his response to the other pilot's runway crossing that he was
getting pretty stressed.
