Common questions
What is a delivery-delay histogram?
It groups deliveries by how late they arrived so the distribution of delays is visible.
Why not use only average delay?
An average can hide whether most delays are small or whether a few severe cases are pulling it upward.
Can I compare two delivery regions?
Yes, if both use the same delay definition, period, and bin ranges.
