OK - I have calculated the Ethiopian numbers in an illustration about the holes theory and also explained the impact on Nigeria on the case numbers this year
I did it for Ethiopia already. Egypt follows the same principles. Again I only have 2013 entrant numbers so I have to base it on that (although it would seem likely that entries have increased.
So the numbers for 2013 are 395k entries plus 565k derivatives. That means Egypt has 2.43 selectees per case including family. I think that ratio would be somewhat the same in 2014 and 2015.
395k entries at AF winning percentage (1.84% from 2013) would mean 7250 cases if Egypt were allowed to be unlimited. In 2014 those 7250 would be spread over 116k case numbers – that is 62 per 1000. (and 72 per 1000 in DV2015 if we assume a 2015 high CN of 100k which might be a little high). The 2015 number could increase a bit (higher density) due to higher Egyptian entries, lower max case number for AF. However, let's take those numbers for now to illustrate the point.
2014 had 5757 selectees which would need 2369 cases (at 2.43 per case). 2369 cases divided by the 62 per 1000 would have revealed a max Egypt case of around 38200. That is almost exactly correct from what we actually saw.
2015 has 4988 selectees which would need 2052 cases (at 2.43 per case). 2052 cases divided by the 72 per 1000 would have revealed a max Egypt case of around 28500. I think that might be a little high - due to the factors I have outlined but I can't be certain.
Most importantly, I believe all Egyptian cases could get current – because the 4988 might not be enough to meet the 7% limit. According to the numbers I gave above, 2014 the Egypt limit was imposed at 32250 around 6000 CNs before the cases would have been exhausted anyway. So – at 62 cases per 1000 that means 372 cases that missed out – around 900 people. The 900 people were the top 900 in the 5757 – meaning 2014 used about 4850 cases – pretty close to the 2015 number. So IF a limit is imposed (as it was last year), it would only affect a small number of cases – perhaps the top 1000 case numbers.
I hope that helps. The highest number I have seen in this thread for an Egyptian is 26XXX - so according to my numbers even that one has a good chance - especially if that is at the low end of 26000 to 26999 range.
