Given different constraints, one gets different ratings. It's like trying to determine the best athlete ever. Home runs? Pitches? Slam dunks? 3-pointers? Touchdowns?

each is a rating for a different discipline... that's why these ratings are separate... they are like tenis, football, hockey, baseball ratings - none of them is your real sports rating...
your rating in these disciplines is not just a matter of your general abilities, there are other important factors for example preference for a particular discipline and many others...
