I was toying around outside trying to lock focus on my friend riding his skateboard and shooting at 2.8 on AI Servo, but I really noticed no issues maintaining focus and getting a pretty good hit rate.

Focus shift is mostly noticeable on when you're shooting certain aperture range at close to minimum focal distance (subject is very close to camera). Otherwise, it's really not an issue at all.

Yes, mine works fine wide open.

This explains the phenomenon better than I can.

I almost always shoot in AV mode to maintain a consistent aperture.
I also set my minimum shutter speed to 1/60 with the 50L.
I also use an ND8 filter that lives on my 50L 95% of the time, from morning to dust.
Keeping the aperture fixed and a minimum SS of 1/60 or more to stop motion.
I let the ISO vary up to 6400 max. Within those setting my 50L and others perform great.

Even during magic hour, the ISO on the 6D is almost noise free up to 1600
If I go out to shoot in the evening and night, I swap off the ND filter.

In all honesty, I'm taking it back to the store and getting the 24-70 2.8 L v2.
And yes, the low sensor noise of the 6D is quite astonishing.

I think ive cured my issues. I re-ran the magic lantern automated dottune about 10 times using a better focus chart that I printed from the net and also increased the number of passes per run to the maximum of 10. I now have a MFA of +1. (Originally I got -3 then got +11!!).

Been taking random test shots at various distances and it seems to be performing as it should. There may be some hope yet :-)

Nothing too exciting, just some thin DOF and creamy bokeh.

Looks like you nailed focus :)
So now that you think you have it dialed in, is it a keeper?

I think so. I was seriously close to selling and was actually hating the lens but now its set properly I'm really starting to like it. Ill give it a good test period now

How close were you to these cats when shooting?

Nailed the focus, btw.

They are not cropped so quite close, maybe 2 feet?

EDIT - exif says 0.54m for the ginger and white cat and 0.47m for the brown cat so both within 2 feet (0.6m)
