Yes, this is the method we used along after hacking up a cubic approximation using
Graphical Analysis. The lookup table is plenty accurate and also demonstrates that
some problems are best solved using nothing more than a ruler and a few spare
minutes. The cubic was really no more accurate for our purposes. It isn't elegant
but it got us through
the maze at the Trinity Firefighting contest.
