So I'm a mad lad.  I actually brute forced it.  Here's a cleverly cropped image designed to be deleted later.  I think the labels got swapped.  Even so, the numbers I was getting did not line up with what brute forcing revealed in the end.  There are two innocent players here which we are in agreement.  I hope this helps!

you need to input all good numbers for the door to open. You might want to download latest version, and check in the walkthrough around 25:30 if it does not work for you. I realize I gave you false information on inhuman, got tangled :(  

croco and poly = 5+4+2

Inhu-el = 4+5+8

for NF you are on the good track, 6+6 and then not +0 but in a possible range if you know what I mean.
