This letter was shown to the author, Dr. Peter Dingle, who agrees with the points raised. He makes the observation that the analysis of results is a difficult problem, but one that should be tackled remember ing what needs to be done to understand the problem rather than what can be done. However, it is always better to be too thor ough than too simplistic.
