400mm f/5.6: Opinion re whether MA is required?

[2slo]

Hi all,

I'm posting this here and in the lens section to get as much feedback as I can.
Could I ask those with experience of microadjusting lenses to take a look at the shot below please and tell me whether you think my lens needs MA. I think it does but, first of all I've never done this before and secondly I've no benchmark to compare it with, hence I'd like opinion please, preferably from those who've done this procedure.
The shot is a JPEG, taken with a 1DmkIV plus 400mm f/5.6 lens. Taken from 20m away (50 x the focal length) 1/400 sec; ISO 200. The camera was tripod mounted and wired remote activated. AF using liveview at max mag was used. 3 shots were taken, all look the same. The only pp was minor sharpening. What you see is a 100% crop.
If you look at the yellow security info on the box, to me that's OOF hence I think the lens needs MA. That's just my opinion of course, would you agree or am I expecting too much?

Thanks

1. Please do not post the same question in multiple threads. All it does is waste space and annoy people.

2. I refer you to my response to your other posting - Which AF mode (p.138 of the manual)?
