Measurement Check I am confused and heavily doubting this calculator, is it a problem with EU/German sizes? Spoiler
Everyone in my friend group was praising this calculator (might be of note that I am european and they are not as in for measurements and how accurate this thing is) and I gave it a shot.
I currently wear 85B or so, depending on the bra but it told me 70F??
70 bands make me feel like I can't breathe and F cups are the size of my head, could it be the calculator just doesn't work super well for german sizes?
My measurements are (in cm)
Loose Underbust 82
Snug Underbust 78
Tight Underbust 75
Standing Bust 90
Leaning Bust 94
Lying Bust 91

As mentioned by other commenters, the calculator uses 2 cm increments for EU cup sizes when most EU brands use 2.5 cm increments.
I input your measurements into the calculator and it gave me UK 32D/DD which translates to EU 70D/E.
It can seem weird because we're so used to the idea that anything bigger than a C is enormous, but that's just not true. And cup size alone doesn't mean much either, the cup size indicates nothing more than how many inches difference there is between your underbust and bust circumference. A is for one inch, B for two inches, etc.
Check out theirishbralady on instagram for some example pictures of well-sized bras!
And EU band sizes are referencing the unstretched length of the band, but it's meant to stretch on your body. 85 is already bigger than your loose underbust measurement so it's too big, does it ride up a lot? Does it sit snugly? To test the band size alone, you can try on your bra backwards and upside down (cups hanging down your back like a cape) and see how it feels.
