3 I think I've spent enough time trying to find a nice analytic way to guess parameters for a Gompertz model fit to my unfolding probability densities.
4 I now have a heuristic which seems to work :p, and I suppose I'll be satisfied with that for the time being.

6 On to find out about analytic solutions to Kramers' unfolding rates.

8 Update: I figured out how to use the [NIST reference][] while writing
9 my [[sawsim]] paper, listing the mean and standard deviation of the
10 Gumbel distribution.  So many names…  Anyway, the `pysawsim` tests
11 now use the [improved guessing procedure][guess].
