Hmm, I think it must be clear. At the top of your table I see: "The upper one is the evaluation difference, in pawns". So, I mean the pair correlation, not the average difference of evals. For example, someone want to create a clone simply changine engine output. For example you can multiply engine eval on 1.5, than it will play the near same strength, but your criterial will show difference. But when you're using the pair correlation it will be clear that it's a clone. Here you can found a formulas and several criteria description: http://www.3ka.mipt.ru/vlib/books/Programming/ComputerScience/Numerical_Recipes_in_C/c14-5.pdf
