Depending on the destination, even with 1 day handle time you might see a pair of dates but not always. With 1 day, a pair of estimated delivery dates would be more likely for a destination that is Zone 5 up to Zone 8.

I normally use 2-day handling time, but I switched to one day last week because my handling time gap is more than 2 days. (2.2 days to 0.1 days) I plan on switching back to 2 day handling time some time about October 20th, right before the new rules kick in.

Starting October 25, to help improve accuracy, we’ll enable automated handling time if your manually configured handling time is two or more days slower than your actual handling time (known as a handling time gap). If automated handling time is enabled for this reason, you won’t be able to disable it.
