FANTASTIC idea, Mogambo!
Judge from your data point, it seems that your DO's lightening fast! I guess you could start a business of renting your address to N400 applicants. 3 months before the application date, people change the mailing address with the USPS to your address, and you essentially become the mailing agents for the N400 applicants from the slow moving DOs like Atlanta. You of course can charge a hefty fee for your service! That will really be a lucrative business plan, won't it?
More importantly, with that, the processing time will quickly balance out across the nation, because the slow moving DOs will lose the applicants.
It is shameful for these slow moving DOs like Atlanta! And the current system is unfair to the N400 applicants from slow moving DOs! Everyone pays the same amount of the application fees to the USCIS, shouldn't everyone be treated the same in regards to the processing time, etc?
