I don't think it is nonsense. I think they may have an idea about estimated completion dates. Actually, their estimations dates matched up with PPR showers dates.
Moreover, I also think August AORs will be expecting lots of good news this month especially ppl with biometrics. I mean we saw a case in which someone even with security screening who received PPR recently.
Just my observations.
An agent on the phone did inform me that my estimated completion date is July 14. my AOR is September 23rd everything is passed except for security screening.
