Just received an email that we got approved. Two days shy of 6 months. I can update my time-line here, but I'm a little nervous to update the spreadsheet as I'm Android only while in Romania and the Google Sheets app says something about not supporting all of the elements in the sheet.
For my fellow RFE victims, if it helps, the RFE was on May 7, they acknowledged the response on May 19, and finally approved on May 27. I suppose it could have been worse and we are thrilled beyond words to be past this stage, but I'm also annoyed that this could mean an extra month apart from my wife for no good reason.
We wish everyone a speedy approval. This process is truly inhumane at best.

Isn't it Chuck Schumer that heads oversight?

I'm just going on memory. I'm too demoralized to go back and double check everything. I noticed another couple with the same PD, same SC as us, doesn't appear to be an expedite, had their interview on 16 April. At the same I noticed a couple just finished up after 14 or 15 months. Seeing that has me thinking of how long it will take before I get fed up enough that I'll just decide to retire (eligable in 98 days), take my pension, my investment accounts, etc and just beat feet out of here.

There are two opposing forces at work here. The first is that processing is supposed to take place in the order received. I don't know all of the ins and outs at the federal level of government, but having decades of experience with local and county level government, there are certain things where extraordinary efforts are made to rule out any possible accusations of improper favoritism. In fact so much so that the entire effort to ensure fairness winds up tripling (or more) the cost of whatever it oversees and inevitably slows down the entire process because of all the inefficiencies.
The opposing force to first in first out is the target processing time which I believe is 5 months, just like the recently updated claimed processing time for Nebraska at the USCIS website. If you are in fact processing in the order received, the only reason to have an "average" at all should be to take into account delays caused by RFEs. Theoretically speaking, were it not for RFEs and assuming FIFO, they should pretty much have the processing time nailed down to the number of weeks per application. But instead we have this nebulous "average" processing time which allows for a substantial amount of wiggle room. Furthermore, I don't know if the expedites are factored into this average or not, but if they are then we sort of have a curve busting element thrown into the equation. It seems like there are a few lucky lottery winners who get processed at the speed of light for no apparent reason, there are a few who languish for a year or more because their file was accidentally used to prop up the short leg on someone's desk, and then there's everybody else.
If the community of people here are indeed a pretty good representation of the actual caseload that USCIS takes on, then you can see some trends that are likely very close to what's going on. The one thing that drives me nuts here is people who fail to update their timelines at all or who update it several months late. It makes looking into the crystal ball all the more difficult.
