on-time delivery policy and shipping settings - shipment or units?
I can't believe I've only just noticed this and I think I've proven it to myself. I'm just looking for confirmation from others who know more.
The OTDR is not based on shipments, but UNITS shipped. So if you think you're going great with only 1 late shipment, if it was for 500 units, you could be in trouble.
I can understand it based on the new policy. If a customer wants 500, they want them by the promised ship date so you 'failed' on all 500 not just 1 shipment. So you just have to deliver another 4500 units to just make the OTDR cut off.
Makes a difference to your thinking about prioritizing orders when units come into play.
Thanks for any feedback.

What is changing?
We are also changing the way we measure OTDR to now measure the percentage of your tracked seller-fulfilled units that were delivered on or before the seller-promised "Deliver by" date prior to promise extensions being added. Before this change, OTDR was measured after promise extensions were added. Promise extensions are additional days that we may add to the delivery date to account for logistical factors that may delay a delivery such as extreme weather, transportation network constraints, or recent history of a seller delivering shipments after their set delivery date. This policy does not apply to offers using the Fulfillment by Amazon (FBA) service because sellers are not responsible for on-time delivery promises for FBA orders.
Going by "units" makes some sense.
- I get 5 orders for 10 units each
- I only ship 5 units to each of the 5 orders to start to avoid an OTDR hit
- I later ship the rest

Hello @Seller_lU3njDwc1tsUG and the other sellers asking about OTDR.
@Seller_Qbd0RsfZFEZBY and @Seller_4Ko0M2LxNBAQN provided correct information: OTDR is calculated based on units and not orders.
"OTDR measures the percentage of your tracked seller-fulfilled units that were delivered on or before the seller-promised "Deliver by" date. OTDR is the average of all of your tracked shipped units, not just a specific SKU or shipment."
There have not been any recent Time Window and Promised Delivery Date updates, and it is displaying correctly.

It took my some time to understand this as well, its not clear or intuitive at all.
But, you are right it should be the date.
And if you look, it is the date as the timestamp is 23:59:59 PDT. So any unit delivered on that date is counted.

Just one question on the last sentence;
"So any unit delivered on that date is counted."
The OTDR calculates by order number. SO your question is a valid one, if the order is a split shipment, how is that calculated?
I do not know

@KJ_Amazon Have you found anything regarding Freight LTL shipments?

Can someone please explain to me, in short small syllable words, as if you were speaking to a child, without regard as to whether the Metric is calculated on units or orders, how, exactly, the date and/or time when an employee of the Carrier drops a package at an address is within a Seller's control and why a 3rd Party Seller should be held accountable for the failures of that employee to fulfill the promises made by the carrier and Amazon? I am sincerely seeking to understand what the goal is?
If the intent is to demoralize and discourge 3P Sellers and drive them off the Platform, then, yay Goal accomplished. But otherwise I am unable to fathom the purpose of punishing me for over achieving.
