They are quite similar, yes...

Would have to have a dig for the more detailed Dan Rather graphs, but the same basic profile...pretty rapid to over-g, then diminishing acceleration.
I'm out of field here, but I doubt that Poly(10) is a great way to smooth an acceleration curve. It may be close enough to draw appropriate qualitative conclusions, but I would expect the hidden assumptions to bite, especially in the presence of measurement error.
This seems like a subtle question in applied time series econometrics, or whatever empirical physicists call their equivalent of econometrics. Like a Kalman filter problem on steroids.
Obviously you've thought almost infinitely more about this than I have. Has there been a good discussion of how to handle the estimation with error?
