Actually, I should have called it 'zone rating', not 'zone range'.

Essentially, you divide the field into zones for which each fielder is responsible. You then calculate the percentage of actual plays made by a fielder when a ball was hit into his zone.
You can also keep track of out-of-zone plays separately.

It's a better measure of range than the pure range factor because it's less dependent on the rest of the team.

See here, for instance:
