Blending correlation of freezing point, flash point, and smoke point

[Dendrobium1975]

Good day,

I would like to know which blending correlation could be used for freezing point, smoke point, and flash point. Do they follow linear or non-linea blending correlation?. For smoke point, I think it should be linear since it represent aromatic content in jet fuel. But please correct me if I'm wrong. I have no idea with two others.

Thanks in advance.
