Just a thought:
Majority of people who applied, did not go on this forum and have no idea that the process is so streamlined that it actually takes less then 90 days.
But i can not imagine so many people who did everything by the book and apply exactly 90 days before, they all get "can'not make decision" answer. USNIC must be flooded with undecided cases like this. But it surely not the case here looking at the statistics.
I think the USINC must have some automatic tikers that will not schedule the interview unless computer sees the 3/5 year anniversary.
And some pure folks just got unluky with comp glitches.
It is not that i try to justify my case to send it right 90 days before, NO, it is just an analisys
