Lou,
Not sure its the same, but when giving design presentations, it is said you should go first or last, lest being forgotten as part of the middle 2, 3 or 4 interviews. I think it would matter more with more courses.
But maybe not. I had one so-called "expert" in presentations explain it this way.
After Presentation no. 1 - leave ranked no. 1 unless you are a real screw up
After Presentation no. 2 - Either first ranked, or out of competition
After Presentation no. 3 - Either first ranked, or out of competition to survivor of 1 vs 2
After Presentation no. 4 - Either first ranked, or out of competition to survivor of 1/2 vs 3
After Presentation no. 5 - Either first ranked, or out of competition to survivor of 3 vs 4
The human brain probably tends to rank things, and in a 2 course scenario, either one could win on merit.
