Fittest Added

Hi All,

I am newbie in octopus and still confuse to decide the cadidates based on the fittest. I have a question, what is "fittest added" in navigation statistics and how to set it?
I always having it 0 when I run octopus yet I see several examples with values in it.

I also wondering is there any ways to get the "fittest" in a value? so that it is easily to investigate besides seeing from the navigation viewcube.

thanks

Rendy
