So I'd say the compute line is correct and you don't need to change it.

We simply try to reflect the physical reality. Given that this physical
reality is complex we limit ourselves to a linear interpolation in the
temperature range we are interested in. Usually this is good enough.

Sorry, there's not much I can do for you at this point. You seem to
lack the basics of linear algebra.
