I used the shortcuts, and made it through NVC in just under 3 months, not bad time wise.
I put all the notes from the forum on the visajourney wiki, so you might check it out.
http://www.visajourney.com/wiki/index.php/Jame%27s_ShortcutWhat I learned was that they didnt seem to care if the form I mailed in was perfect, so long as their readers could process it.
I really think the NVC people work hard, and try to help you when they can.
If I was you, as soon as I knew the forms were generated, I'd send them in as fast as possible.
It was a 2 week cycle for almost all my forms.
I'd mail them next day delivery, 2 weeks later the phone message would change
