Actually my point was that there is probably nothing to correct.

How are we supposed to guess? We would need many data points to decide
which is best, and you did provide only one (which may not even be
correct.)

We use the formula which gives the best result for the applicable range
of temperatures. There's little point in having a slighly more simple
equation if it gives less accurate results.
