Iran in DV-13 before additional notification had 6029 winners in DV-13.
CEAC data for Iran before number 9413 (where the break is) has 3386 family members, and 3536 total (after additional notification). THat means the number of iranian winners after it would be
3536/3386*6029 = 6296
Same for Nepal 3057/2794*4370 = 4781.
Same for the rest of Asia 3163/2865 *6854 = 7567.
Now. New number for Iran in DV-14 6027.
6027/6296*10682 (max number in dv-13) = 10225 (max number for iran in dv-14).
In the same way for Nepal, new number 6082
6082 / 4781 * 10682 = 13590 (max number for Nepal).
For the rest of Asia new numbers in dv-14 is 11161 = 23270 - 6027-6082.
So, 11161/7567*10682 = 15760.
So, if both Iran and Nepal have special kimits, the max for other countries would be about 15760.
Another way to do it is to say that if 11161 (rest of Asia) are spread out until 27000, then 7567 (needed to fill the same quota as in DV-13) would end at 18305.
If, on the other hand, Iran and Nepal do not have special limits, the asian max number would be
27000*(6296+4781+7567)/11161 = 21630.
So, any way, the expected limits for Nepal and Iran would be (if implemented) around 13600 and 10200 correspondingly. And max for Asia would be about 14000-18000 if both Nepal and Iran have special limis, like Ukraine and Uzbekistan, or about 20000-21000 if no lomits like that exist.
