-* $`id(A_i,B_i)`$ is the identity score for each BBH pair between element $`A`$ and element $`B`$
-* $`min(P_A,P_B)`$ is the number of proteins in the smallest of $`A`$ and $`B`$ elements.
+* $`i`$ is the number of BBH between elements $`A`$ and $`B`$
+* $`id(A_i,B_i)`$ is the identity score of BBH $`i`$
+* $`P_A`$ and $`P_B`$ are the numbers of proteins of $`A`$ and $`B`$ respectively
 
 **NOTE**  
-`wGRR` calculates 3 versions of the wGRR depending on which BBH pairs are considered (numerator) and what proteins should be counted (denominator). See the `Output` section of this manual for more explanations.
