Overflow Sorting

Why do most people feel the need to sort their overflow by “sorting letter” and not by “driver aid number”. I get certain overflow match to certain totes and that can help, but that just seems more confusing. I’ve personally found it easier to go by grouping the overflow into stacks starting with the first digit of the driver aid (i.e. 600’s, 700’s, 800’s). Obviously like anything with Amazon, it’s not a perfect system. But on days I can load it properly and not get rushed, I feel it makes finding overflow much easier throughout the day.

Am I missing something with organizing by letter that might be better?
