That is the million dollar question and unfortunately in this process we aren't owed any answers from the government so we will never know.
Nobody on the Kingston thread that applied in 2013 has gotten through yet...so the ones you are seeing as landed on the spreadsheet are probably from Feb 2012.
Hopefully Kingston will process the 2012 applications and then the 2013 applications so we can all be with our significant others sooner than later. Kingston claims to process the applications in order of receipt; however, it doesn't always work that way...
Until then, we wait, and wait, and wait, and wait...
