Sloped Minifig Leg 3817b is wrong

[Max Martin Richter]

For the brave soul who will cope with this correction, here is a leg mesh extracted from 3D catalog, compared to 3816/3816b.
Bottom stud hole is not aligned with joint hole, measured offset at center of stud hole is o.7ldu. BUT stud hole is weird, longer in z direction by more than 1 ldu!

I will compare with the real part. But as far as I can tell, the drawing in the initial post seems to be correct.
After thinking what 1K and 1P means I came to the conclusion that it is 1 brick (Klodser) and 1 plate (plade).
