Using the AF-C and AF ON method is no solution for D800.

This all sounds like a joke - but I´m not laughing.

I´m beginning to understand why I get these very inconsistent AF results from my D800...

I have no left/right AF issues, I have issues getting the center AF point to give good results.
It doesn´t matter if I´m set to AF-C, single point or dynamic, or AF-S. Results aren´t good.

All to often foucs is not where I wanted it to be.
Furry animals, like foxes, deer, dogs and horses, at longer distances than a few meters seem especially hard to get in good focus whether moving or still.
