I suspected this to be the case late last year. I had a 5 at-a-time subscription and found myself waiting for several days for new discs to arrive despite having returned the previous 5 individually for the most part. I noticed that no discs were ever shipped to me on a Monday and very rarely on a Saturday, but multiple discs always went out on Tuesdays.
I tried holding onto discs and returning them in bulk on different days of the week in an attempt to break what I figured was an unconscious cycle that I had fallen into. This didn't help. I eventually downgraded to a 4-at-a-time sub. and now I cycle through 2-3 discs more per month than on the higher capacity sub. Only took me 2 years to figure this out.
