Note: Only Data in which the correct spelling was found in all three dictionaries was counted.

The Score is a weighted average which gives more emphases to words found earlier in the list. See weights.tab for the current weights. The exact weights are subject to change.
First is: (Total Found First On List)/(Total)*100, 1-5 is: (Total Found 1st - 5th)/(Total)*100, etc...
