6D Af is good only at central spot in One-Shot mode.

6D ai-servo test here

Many times it is the technique used that makes the difference.  I have allowed others to use my camera with the exact setup I use shooting the exact same event I am shooting and they often get 50% less keepers due to their technique.

Thanks for more informations, it's helpful.
Few questions
- Have you used 5D Mark III or 1D Mark 4 on dogs? If yes, what was the result in contrast with 1Dx?
- "ITR on" - does it influence on the result?

Adds color detection to AF system so it should be better at tracking things if the color is different from the background.

does it work only in "61 points automatic selection AF" ?
or does color detection work in Zone AF and Extended too ?

So first of all servo AF is not always 100% no matter how you have your settings. 

The lens and camera are both top of the line. 

I think, I need to change camera for 1 DX, will it make result better?
but if af of both cameras is the same, so will result be the same ?
also 1DX have more power for USM may be it wiil help ?

My fav AI servo is case2 with 4pts AF expansion mode.

Shooting info: Tv, 1/800

in this samples you have large DOF, but on the tele + f/2.8 dof is very small

Check your AI Servo Priority setting.  Looks like you could have it set to Release/Speed Priority rather than Focus Priority or Equal Priority.

I tried
defalult for both (Release Priority and Speed Priority), Focus priority for both, Release Priority and Focus Priority

2. af in 5diii is better than in 1dm iv
3. af in 5diii is the same as in 1dx

I have 5d mark 3 and 70-200/2.8 ii lense.

Sunny day I tried to make shots runing dogs.

I tried to use ai-servo, case1 and case6, zone af points and one af point with ext, but everytime i have 50% shots with missing focus.

What i do wrong ?
