That's like claiming that gas mileage is the only way to evaluate a car, and when hearing someone say "only a fan would think you can make a decision like this from a single number," asking what you would use instead of gas mileage You can't even evaluate if a good choice for location 1 is still a good choice for a different location without knowing what the other location is There is no easy number for a casual to try to make these decisions with
