The manual setting are for your weight and a good starting point, anything past that is for how YOU ride and how YOU like it to feel. Theres no magic setting, and no one can do that for you.
Try searching "Dave Moss" "2 clicks out" on you tube to explain what each setting does and what to change to make your bike behave the way you like it too.
Its a fun process, and impossible to screw up. All you have to do is turn settings. You can always start over.
