The exhibit you're referring to definitely highlights that many of them were subject to a manual review.
The automated reviews were just checking addresses, making sure direct deposit information hadn't really changed and looking at reasonableness of payroll. There were a large number that were then subject to some sort of maybe verbal update or verification or some other information that was collected. Again, there were very minimal checks, and hence few were actually rejected in the beginning, which emphasizes the back-end work.
