LR5, Canon 6D, Mac and WB issue!

Question

So I just upgraded to LR5 and I'm finding that my white balance is different in LR5 vs LR4.  I had the same problem when I updated to the latest version of 4 (so I had to reinstall 4.3 and all was well)  I figured it was a fluke and didn't think I'd have the same issue with LR5...Anyway if I try to correct skin tones in LR I like to be able to check what my eyes are seeing (on my calibrated screen) by using the RGB numbers.  Typically I find that if I choose a midtone with 85% luminocity and adjust from there letting my numbers fall in a 20 point spread (r=85, g=73-75, b=65-68) I can get a pretty good rendition of my children's skin tones.  This method works GREAT in LR 4.3 but in LR5 NOT AT ALL. LR5 wants me to add way too much yellow (warmth) and magenta (if anything with Canon, sometimes the images have too much magenta in them to start!)  I like to be able to do some quick edits, but if I have to second guess my eyes and don't have solid numbers to check by I'll be adjusting each image to death and second guessing my eyes!  I can use LR 4.3 YES, but I just PAID for 5 and would love for it to work right!   I was just curious if anyone else has noticed a difference in how LR5 was interpreting WB/colorspace or if it's just me!  I am callibrated and even tried recallibrating (didn't change a thing).  Also, it seems strange that v 4.3 is fine as is CS6 but 4.4 and 5 are reading my images really wrong....Thanks is advance!

Here is my image in LR4 with only WB corrected (sample taken from back of left arm)

And HERE is the image in LR5 with the same WB settings from LR4 (same exact sample point)

As you can see, even the luminosity of the skin is different in LR5...strange right? 
So I found a point of 85% red on the image in LR5 (this was the back of the right arm)

As you can see LR is telling me that I need to add magenta and warm it up....
Here is the same image pulled into CS 6 to check the WB (point sample from back of left arm)

So I was curious as to what LR5 wanted my WB to be so I attempted to correct it by the numbers:

YUCK right?!?!? Look how much magenta I had to add (I can't even get the image to say it has 74-73% green unless my image looks magenta-like the skin is actually pink LOL) and it's way too warm
So of course I pulled it into PS and you can see that it's too warm (although surprisingly on this one the magenta checks out...although if I cooled it down it would probably show too much magenta then)

This is really annoying and frustrating!  I do shoot in raw so I could put the raw file in dropbox later if anyone thinks they could have a solution.  And I am using Adobe standard in both LR4 and 5.
Thanks
