unique/duplicate factors question

[Moo_the_cow]

Suppose a factor for a k/n pair is discovered at 400T today. Next month, a factor for the same k/n pair is discovered, but it is at 360T. Which factor is the unique factor, the factor found first or the factor that is smaller?

P.S. I think that this question has been asked before, but I somehow can't find where it is.

A unique factor is the first factor found for a candidate.
Before 21-July-2003 scores were calculated as follows:

The lowest p for a k/n factor scored as the unique factor, all higher p scored as duplicates.
