I think it's been made clear (in your previous inquiry) that there is no ONE person you can contact to inquire about the status of your application -- as aggrivating as that is, and I completely empathize with your frustration.
PrincessJuls is right. You're right on the dot for 20 days and the timing for when it was received seems to have fallen right in their peak for a heavy volume of apps. Easier said than done, but you really have no choice but to give it more time. (Bare in mind I couldn't follow my own advice now at the time of my own application, but understand we've all been through it and it won't help to stress about it.)
If it makes you feel better, contact FedEx and find out the name of the individual who signed for your documents and make note of it. I know they shut early on a Friday during the summer, so chances are that although it was delivery confirmed on Friday at 10am, it may not have been hand delivered FROM that person until closer to closing time.
I'm not sure how they sort documents, but it may be helpful on their site to display the proceedure or process (or channels) a package must go through -- especially in times of heavy volume or backlog -- before it gets to any one individual's desk to be reviewed...all this being so that applicants have a better idea of how many hands it must pass through before arriving on someone's desk for a decision.
All that being said, although 20 days is the approximate timeline at this point, other applications may take longer. Do you feel your application was pretty straightforward? The NY office was efficient in my own case and in most other's I have read. I would venture to say you should hear something this coming week as I, myself, would have begun counting from that following Monday. All you can do at this point is be patient. The people here in the Visa forum have mostly all been through the process (or are currently in it) and we know the anxiety.
Shame we can't put GPS on our packages...hang in there.
