Thanks Joshua, so ELO RANGE= min score to max score
+- figure= (max-min)/2
To improve your list I would suggest adding the number of ratings used for a
specific engine, to help the interpretation of these. Is it possible to get any
further data from the server? It would be nice for instance to know the range
and average of the CPU speeds used (duals etc may complicate this).
