Monday is Netflix's busiest day

According to the data collected by Listology's Netflix Tracker, most returns in one day are on Monday, so I used to think Tuesday would be the busiest processing day at the Netflix distribution centers. However, since they don't process mail on Saturdays, anything you return on Friday or Saturday will get processed on Monday, which makes Monday their busiest day instead (if your distribution center is nearby). Listology has tracked over 4000 Netflix rentals, but they have complete data on about a fourth of those. You can examine it yourself.
