But I guess you could use more advanced interpolation/extrapolation functions as well
If you are interested in the interpolation function that is used by openlane, I think opensta does it

Yes, openSTA uses bilinear interpolation, but I dont know whether it is a good idea, because atleast in Sky130 std cell libraries, transition times and load caps have geometric spread.
