Understanding rating - Page 1

When looking at litters and evulating would like opinions on following:

Would this be considered positive for someone wanting strong nerves, confidence and working ability. Many other factors of course but the nerves and confidence a must.  Not wanting extreme never settle down drives but high drive .

I understand a "5" rating is ideal and my question is really about the "1" in both ratings which I understand means the dog is very aggressive or sharp. Has anyone any experience with these rating's on the type of pups they might produce when both parents have the "1" ?
