Two steps as good as three, maybe better?

Everything looks pretty good with two Gauss-Newton steps.

There's a mix of wins, losses, and ambiguous changes here, with many
more wins than losses.  I definitely wouldn't be eager to land the
inverse of this change: slow things down, fit one or two profiles a bit
better, and fit a whole bunch a bit worse.
