... and it also has completely different data points.  Just because 
somebody managed to fit a tangent curve to one dataset doesn't mean you 
can fit one to whichever dataset you find.  It doesn't even necessarily 
mean that the fit this person did is meaningful --- at 4 parameters from 
10 data points, and quite visible deviation, it just as well could be a 
fluke.
