Assign each letter in a word a score corresponding to its position in the alphabet, so a=1, b=2 and so on until z=26. The total score of a word is the average score of all its letters.
What is the highest scoring word?
Words need to have a minimum of four letters ('zz' is not word as it would make this puzzle boring) and appear in a standard dictionary (in case of dispute, I will use Merriam-Webster).
Example: the word 'ball' has a score of (2+1+12+12)/4=6.75
