There came quite some reactions and suggestions on my first post about another way of ranking the international top scorers. I can only agree with the main criticism: the measure of how valuable the top scorer is, could be better contrived than by calculating the average elo-points of the opponent per goal scored. This measure indeed mainly indicated that some top scorers played mostly weaker opposition.
Some suggested to not take the average but just weigh the goals with some weigh factors. I agree, each goal scored should contribute -more or less- to the total score of a top scorer, not carry the danger that the total score got reduced.
