Check it immediately after a trip. If you see bubbles on the dipstick, then you know its so high its getting churned by the crankshaft. If no bubbles, it is fine. My guess is it is not enough overfill to be a problem at all. No bubbles, fine.
Possible overfill?

yes this is the 3.5. So do you think I should drain a bit? I can't imagine it being that much. I put in 6.2 quarts. Maybe there was some residual hiding in the transmission cooler line?
Having that much in extra should not cause any foaming or any harm correct?
Yes some "residual" oil remains so if you keep adding 6.2 quarts with each oil change and you are only drsining 6.0 quarts because 0.2 remains as "residual" then you can see you are creating an overfill condition more and more.
You can measure exactly how much oil you remove and then add an equal amount at similar temperature or use the more common practice...Ause the dipstick since it is designed to prevent this overfill from occuring.
Stay within the hatchmarks of the dipstock and there is no need to fill to the top MAX mark. The engine is designed to function anywhere between MIN and MAX. There is no wrong answer if you remain between the two.
Is it worth drainng some out now? Probably not.
Is it a good practice to always run above MAX? Probably not.

4x4 (should) have a deep pan, baffles and proper windage control for all attitude driving. Where do you think the oil is piling up when climbing a 30% incline? Or down same?
If it was a 1/2 qt or more I might take some out. Not here.
Back in the '90's My wife had a quick oil change place change her oil once - but they didn't take out the old oil. Now that caused a problem! When I got to my BIL I drained 4 qts and got near the full mark on a 2.2L Impreza.
We NEVER go to a quick oil change place anymore.

Great idea. Wait until signs that damage may be occurring to the engine and then do something about it. Just another example of why I do not buy used cars.

Not on all cars. The way the baffles are set up in the oil pans, I cannot do so on either of my hemi's. The pump tube will only get down far enough to remove a very small amount of oil. Can't do it on the BMW either. No dip stick.

I took a 60cc syringe and plastic tubing and drained 3 OZ. I didn't see any major bubbles on the dipstick prior. I did see tiny almost invisible dots. Hard to say if they were bubbles or specs of dust.
Perhaps paranoid. Better to drain 3 oz than worry about foamimg.
