That's awesome that your "application being prepared" email came so quickly! Seems that the people who were able to do the full upload are moving a lot faster so hopefully your decision will come this week 
Just so you’re aware, the ‘application being prepared’ email is just an email to say that they have the documents and your application has been put in the waiting line along with all the other applications.
Before the new system, your processing time count didn’t start until you got that email. Now, we’re not quite sure if the processing time starts from when New York get your application, or when Sheffield get it. No one will actually look at it until the day the decision is made.
Anyway, I would allow for another 30 working days from receiving the email, though it sounds like it could be quicker than that.
