Guess what lens it was...I'll give you a hint: it's notorious for focus shift. Combine that with often hopeless outer AF performance of the 5 series and, well, the images speak for themselves.
I own the 1Ds3, 1D3 & 1D4. I get OOF shots with those also. And I have been shooting with 20 other cameras with AF the last 20 years. And got OOF shots with those also. Anybody that belive a camera will give you 100% in focus shots, is just a dreamer.........I don't get perfect exposure on all my shots either

In and of itself, that is true. But to pretend that the 5D will focus as well as the 1-series - ESPECIALLY when you get off the centre point - is fantasy.

if it is closer to MFD, why would the thumb in #2 and the finger in #3 be in focus ?
the thin DOF with an 85mm 1.2 or a 50 f1.0 would give you crappy results like this if you wernt paying attention to the DOF. and your distance from subject...

And you expect that the 5D should focus as well as the much more expensive 1 series Pro bodies then

No, not at all. Of course not. But that's a long way from pretending the AF on it isn't very good, especially away from the centre-point.
Of course you can get OOF shots with the 1-series. But it's a huge amount less.
Let's say you get 90% of the 1Ds3 shots with good focus. And 80% with the 5D. But you have to pay a few thousend dollar more for the 1 series. So I belive it's only fair and as expected.
AF is just a tool to help you when shooting. It's not a thing that gives you perfect photo's every time. It's the same with the exposure metering. Most of the time it will give you good exposure. But not all the time. And it's a bit better on the 1 series also.

Man, I get way more than 90 per cent with a 1Ds. And the difference, away from the centre point, is a lot more than 10 per cent, but I haven't got any hard numbers, so I'm not using any.
I love my 5D2. Ive had mine for more than 2 years. IQ as good IMHO as a film Hasselblad, astonishing low light high ISO sensor, large detailed prints to kill for. I've very little interest (probably) in the 5D3.
You can tell I love my 5D2.
And yet in terms of outer point AF performance my 7D kicks its butt. Comprehensively. No argument I've lost shots using the outer AF points on my 5D2. Its not a matter of technique. For the 5D3 I hope Canon give it some 7D AF magic, because it needs it.
I have my 5D2 set to not AF when AF is impossible.
Around 30% of the time in EV < 5 situations the camera will just blink at me and not focus using the peripheral AF points. Switching to the center point results in it locking focus instantly 90% of the time.
I have no issues with the 5D's af system, it's the sensors that are the issue. The gap in sensitivity between the cross type center point and non-cross peripheral points is just too big. The peripheral af points need either very high contrast patterns, lots of light or preferably both. I didn't even know they made cameras with only 1 cross type sensor until I switched to Canon. Almost all of Pentax's cameras use a 11 sensor / 9 cross type AF array, to include their entry level models. Even their tiny K-m that only had 5 sensors had 5/5 crosstypes.

I don't have any hard numbers either. It was just a comparison between those bodies. But if you get way more. Then you probably get more than 100% That's really good.
So why don't you buy a 1 series if you get that much more keepers? Instead of using a camera that you don't like!! Even the older low prices 1 series bodies that are really cheap, have nearly as good AF as the new. You really must like to torture yourself
I have a 1DsIII, a 1DIV, and two 5D. I wouldn't keep the 5D if they couldn't AF. Of course, they're not as good as the 1D-series bodies, so I use different cameras for different situations. Don't expect a 5D to shine in circumstances that require a 1D. Otherwise, if you can't get 5D images in focus with centre point AF then there's something wrong with the gear or with you. It's probably most often the latter.
This doesn't prove anything.. it would be so easy to replicate these focus issues it's not even funny. Back button focus, release button, move camera backwards, take picture. Or just mess up the MA.
User error when using back button focus could also be the issue.

+1
even with my old 10D I could AF. And the 5D is a lot better than the 10D
