Mac Studio Fix Powder Foundation Nc35

OK I finally got officially foundation matched by a MAC MA the other day. She matched me with Studio Fix Powder in C4- on application it looked good but it did shift a bit and turned orange. Then I tried NC40- she says it's more beige than C line. Did the same thing but upon application the tone was off not enough yellow. Then I wanted to try out C35- she says this is too olive-green toned for me and NC35 would be better since she thinks I have more of a golden beige skin tone ( plus it was the color I used in the past- pretty good match but not enough yellow for me. )
OK here's the question- if she originally matched me up with C4- is it that much different than C35? I thought C35 would have been a better match since it seems like the NC line doesn't have enough yellow or is C35 much more 'Olive' than C4?
Side by side it doesn't look that much different- I was too tired to try out C35 and just got NC35 but should I really have gotten C35 instead and not listen to the MA and trust my instinct?
TIA!

I found the stickied foundations thread but it was too scattered and difficult to find info in it, so I hope this thread is o.k.! Otherwise, mods, do with it what you will.
I am especially hoping for Kryolan equivalencies since their foundations are tailored towards HD TV and will probably be awesome quality like everything else they make. But any other foundations for NC35-ers are welcom!
My MAC color in Studio Fix powder foundation is, obviously, NC35. It definitely can make my face look sort of chalky or bumpy if I apply too much, but I use my trusty old kabuki brush to buff it into a very well-moisturized face and it looks nice. I like heavy coverage foundations, to be honest, despite not having too many pigmented flaws..it's more that I have a sort of porous texture and some broken capillaries under my nose and above my lip that thicker applications neutralize. It's also not the best for my oily complexion but I use Kryolan's Anti-Shine powder for that. It has a slight tendency to break me out but all in all I've rebought 4 or 5 times because it does make my skin look even and retro-matte with proper application.
I currently use MUFE's Face & Body liquid foundation which lolariously is labeled with their complicated numbers and French abbreviations instead of Sephora.com's word-names. The label says Réf #31601 which upon Googling suggests N1 Soft Beige,' so I'm gonna go with that. (Also, I'd like to add for the curious that MUFE F&B has amazing coverage and a lovely smell. It feels very 'wet' and moisturizing upon application. It has a strange jelly-like consistency in the bottle but you shake it up and it applies fine. It makes my skin have this ethereal almost Barbie-like glow and covers up the redness under my nose wonderfully.
So to keep it simple, these shades work for me:
MAC Studio Fix powder foundation NC35
MUFE Face & Body liquid foundation N1/Soft Beige 1
MAC Blot powder (loose/pressed) medium dark
Kryolan Anti-shine powder
Biotherm Forget It concealer 30
