From your empirical data it looks like no more than 5 linear sections (see red lines in figure below) would be needed to characterize the curve quite well.
This would significantly cut down on the number of computations needed to return a result, and in this case it look like it might even more accurately fit the input data.

It's easier to generate the polynomial with software (completely avoiding any transcription by hand or hand calcs). This is unless there is a piece-wise linear approximation tool I am unaware of.
Also, for simple math, it's not really a concern when running on the cRio.
