IMD rating: A "perfect" table will be rated at 100; lower values are worse. For each (valid) cell in the table with a frequency-difference value less than 35, a value of (35-diff)^2 is added to a ratings total (the squaring is to make low-difference values detract more from the IMD rating). The ratings total is then divided by the number of selected frequencies and again by 5, and then subtracted from 100 to get the IMD rating.
