Details:

This problem effects relaxation curve fitting in all relax versions.  The
issue is that errors are calculated for each spin and then averaged due to
the low sample number (2 or 3).  Rather than the variance being averaged, the
standard deviations are averaged.  This is statistically meaningless.  For
more details, see
