Shadows of the Past Attribute Generation Method

I noticed the above character attribute generation method with the online tool and was wondering what book it was in? I find the default attribute generation too easily abusable as my players were creating sup pc’s.

Also, are there any other alternative methods for attribute generation in any of the other books?

Conan 2d20 core rules book, p.50 - there are some other alternatives for character creation described there, too.
