This example was very helpful, thank you! I think the bit we were missing was that person C would get their second choice over person E getting their first choice, with all this talk about the applicant being preferred and so on. I've just been wanting to wrap my head around the idea that the only way to go forward is to rank based on preferences solely, which I know to be true from reading it over and over, just have been needing to get it in my head!
Thanks for this example as well! Helps me to understand.
