As far as I'm concerned Greece doesn't participate in such a great amount in the us lottery...
The question is not about Greece or about the significance of add-ons or pop-ups from Greece. It is mainly the general question of understanding whether winner numbers published in visa bulletin include family members. Greece is a perfect example to look at it from another perspective.
The situation with Greece is the following:
2001 63 winners, 38 visas
2002 44 winners, 39 visas
2003 41 winners, 41 visas
2004 66 winners, 58 visas
2005 78 winnerd, 62 visas
2006 68 winners, 54 visas
2007 41 winner, 55 visas, 14 difference
2008 77 winners, 84 visas, 7 difference
2009 63 winners, 76 visas, 13 difference
2010 48 winners, 43 visas
So, out of those 10 years in 2007, 2008 and 2009 Greece produced more visas than winners. Without add-ons and pop-ups that could not be the case if winners include family members (visas do include them). So, we are discussing whether the amount of winners include family members. So, results from Greece could be explained by add-ons and pop-ups. Another source for differences like that is change of chargeability. You could be actually charged (upon issuing a visa) not only to the country from which you registered to the lottery. You could be charged to the country of birth of your spouse or sometimes of your parents. Or even like this:
9 FAM 42.33 N4.3 Errors in Choice of Country of Chargeability
(CT:VISA-1478; 08-26-2010)
If the entrant chooses the wrong country of chargeability at the time of the initial entry, the error will generally be disqualifying. However, if a DV
applicant chooses a country of chargeability during DV registration that is within the same geographic region (one of the six) as the correct country of chargeability, and you determine that the applicant gained no benefit from his or her error, you may continue processing the application.
So, if you were born in Greece but somehow registered as a participand from Turkey, for instance, by mistake, you will not be disqualified and you will still be issued visa under Greece.
Also, if you were born in Egypt, but your spouse was born in Greece, you could still be issued a visa under Greece even though you initially registered under Egypt.
Also, the same situation about children. A child could get a visa under either parent's country of birth, or under his own country of birth.
In 2007 the fraud level I calculate (in order to make frequence of wins for Greece the same as in Europe in general) for Greece was about 18%,
in 2008 it was 0
In 2009 it was 17%
In 2010 it was 27%
In 2011 it was 11%
