cantwaitlonger,
A great find!
It gives insight into the number of approvals from local offices, even if we don't know which EB Category or Country they are in.
It shows how the backlog has reduced, the number of cases that were Current and could be approved from the LO itself. It also shows the Approval /Denial rate.
It perhaps also shows a baseline of cases that are now pending on a monthly basis after the USCIS memo requesting pre-adjudicated cases were sent to TSC.
I don't think I have ever seen a document giving such a detailed peek into the Local Office processing.
