D800 focus with 1.4 prime lenses is very variable and inaccurate

Sorry, I don't have this installed and won't be installing it. The camera focused where I placed the focus sensor box, perfectly over both faces. Literally couldn't have been any better. Even on further testing slightly off setting left to right or up and down didn't help the system grab focus. I know you are thinking "user error", but in most other situations I get 100% perfect focus. I have been using DSLR's since they where created, I know what I am doing. The system just can't handle what I want it to be able to do...
