[CQ-Contest] Unique WPX callsigns worth it ?

[Mike Smith VE9AA]

What are people thoughts on using a totally unique prefix in the 2 x CQWPX
contests? 

 

Do you feel it increases your score any appreciable amount ? 5%? 10%

 

Not being assisted very much I have very limited experience "clicking on
spots" but I can at least imagine a scenario whereby S&Pers are only
clicking on Mults and not also regular Q's who would not have a unique
prefix...but how much, I have no idea.

 

Thoughts?
