"Is Focal reliable ...cant' believe there is a right AF problem as well :-)"

Given all the left AF focus discussion here & on internet I went nervous with my D800 as well . After a lot of reading in discussions which are beyond my technical horizon I decided to buy Focal and test ..with very mixed results so far.Following all the steps

- target printed on mate /heavy paper

- correct lightning

- tripod and no battery grip

I get a- 8 or -11 AF correction for my 24-70 F 2.8 ...which is maybe okay or not . But more surprising is the test of multiple /border AF ...which shows that my outer focus points have a higher accuracy then my central AF point .This can clearly not be the case ... and I aligned both camera and target .. so wondering now .Should I now

- forget to worry about AF and D800 and go out shooting

- be happy that I do not have a left AF problem

- be worried that I have instead a central AF problem (first one here in forum

- start a new alarm on a D800 right focus issue (just kidding)

- or is the overall test not reliable and I should look for the next test ?

Here is the result as screenshot showing central vs out AF point accuracy...oh surprise .. looks like I cant attached a screenshot sorry as basic member ...but you would see that focus on right side is red ...and center AF is not best focus point. If allowed I will link to my post in the DPreview forum :
