I'm not a mathemetician but that equation is probably good enough since...
our acceleration data is fairly easy to "fit". There aren't any inflection points or widely spaced data points.
At work I see lots of complicated equations for various curve fitting techniques (to measure cell growth/death over time in the presence of drug)...but that's for data that's all over the place. It's interesting to see in those cases how a slight change in the equation can make a noticeable difference in the curve fit using the same data points. That's why I raised the question.
I still think error bars would be good so that people can see the inherent error in the technique when comparing numbers...though I'm not certain you can calculate error on these curves. (?).

Yeah, the data is pretty easy to fit. You can include error bars with the acutal points, although
I'm not really familar with their use, so I'd need a little tutorial in order to have them mean anything. :-)
