Suppose you have a new method "M" for "averaging" a particular value for cities -- for instance, "cultural diversity"-- which you measure against some standard ... perhaps the value of New York, which you define as 100.
With this method—that is, using this method—you come up with the following values for three cities:
Toledo 84% of New York
London 103% of New York
Delhi 117% of New York
There are also other averaging methods, A, B and C. With these methods, you have the following values
measured with measured with measured with
Method A Method B Method C
Toledo 65 75 72
London 93 94 89
Delhi 98 101 98
Your method, Method M, gives higher values relative to New York than any other method. That doesn't mean it's a better method, or a worse method—it just gives different results.
