This is an attempt to figure out some strange things.
1. First of all, May visa bulletin references a cutoff from Europe as 40,000
2. Nobody has ever seen EU rank number larger than EU31,999.
My suspision is maximum numbers ever seen in this lottery (DV-2012) per continents are:
South America 1,589
Let's see how close my suspicion to reality is.
Please post your approximate numbers here (you can x-out two last digits)
My suspicion is also there are unpublished numbers, like numbers between 32,000 and 40,000 for Europe.
