As far as I know the category for EB comes into play only at the 140 stage. Beyond the 140, it's clubbed together as AOS for EB applications.
The processing dates published by the service center are only indicative of the earliest date from which they have unprocessed applications. Any date after that is fair game (I've seen august and september 2002 approvals from VT here and on Rupnet, even though their official processing date is january 2002).
