I have just had my upgrade and I didn't pass outright. I have another two months to submit more material before they decide. To be honest, I completely agree as I didn't have enough data prepared but ran out of time. They were very complimentary about what I had done though. I felt fine about this until I started asking around and everyone else seems to have been upgraded immediately. Please tell me I am not the only one!

This is only my opinion but I wouldn't worry too much as they were very complimentary about what you had done (the quality seems to be there) but red tape and a need to cover their backs probably means they can't upgrade you officially until you have more data (you will get there!). Just doing things by the book most likely.
