A LITTLE UP, A LITTLE DOWN…MUST BE SUMMER
Another solid, if uneventful, week in mail delivery. All categories were a touch better than the same week in 2021, even adjusting standards.
For the week beginning July 4, 2022, First-Class letters were delivered on time 94.65% of the time, better than last week, while First-Class flats were delivered on time 90.53% of the time, a bit worse than last week.
For USPS Marketing Mail, Letters were delivered on time an excellent 97.49% of the time. Marketing Mail Flats were delivered on time 95.82% of the time. Marketing Mail in general has been very consistent in on-time percentages since winter.
Average Intra-SCF delivery time was 1.97 days for Marketing Mail letters, 2.27 days for Marketing Mail flats.
GRAPH OF THE WEEK
Here’s an eye test for any statistical nerds out there…like me. Does On-Time delivery have a relationship with average delivery time? Turns out it does (whew!) The top graph is average delivery days – how long it took the average First-Class flat to deliver, YTD. The bottom is on-time %. The two should have an inverse relationship, and they do. When delivery takes more days, on-time % goes down. Seems obvious, but it doesn’t have to be. This is just for First-Class Flats.
There is also a slight improvement rate for both graphs.
