Also, if you do have many data points and are looking for an equation that best fits/models the phenomenon, you may also consider asking the question on stats.stackexchange.com.

comment square footage to non linear time
I am closing the question in its current form as unclear: the question concerns the mathematical modeling of a physical process, and so much more information about the physical process being modeled should be given. You have given us 3 and a half data points, with that it is really doubtful any good mathematical model can be made. You should either tell us why it is the time behaves so non-linearly (including all factors and how they impact your estimates) or give us many more data points so an empirical model can be written down.

comment Why is the permanent of interest for complexity theorists?
For the benefit of those who are not aware of the term permanent: here's the Wikipedia entry. It is defined with a formula that is exactly like that of the determinant, but without the "sign" for the permutation. So that the permanent of the matrix $\begin{pmatrix} a & b\\ c & d\end{pmatrix}$ is $ad + bc$.

comment Establish a trigonometry-based $floor$ function
@barak: all I can say is, do not use the $\lceil \cdot\rceil$ notation when you do not actually mean the ceiling function.

comment Establish a trigonometry-based $floor$ function
@barak: yes, and $\lceil x - 1\rceil = \lceil x \rceil - 1$. The rest I certainly hope you can do by yourself.

@barakmanos: $\lceil x \rceil = - \lfloor -x \rfloor$.
