Around 1.6 or a little higher.
OC is pretty easy to understand.
We know the max case is around 2600 (based on feedback).
We know the disqualification rate for OC is about 7% or a little less (based on recent years).
Assume the derivative rate is 1.6. (based on recent years).
So - 2600 case numbers, of which 7% get disqualified would give 2418 cases.
2418 x 1.6 = 3868 which works out pretty darn spot on to the 3863 they announced.
And for those that like numbers - again, this is all quite easy in OC.
Using DV2015 OC response rate and the issued rate can show roughly how many visas they would need to serve the the 3863 people selected.
Response rate from DV2015 - 46%
Issued rate from DV2015 - 72.75%
So - that means 46% of the 2418 cases (calculated above) will respond - 1112 cases.
72.75% of the 1112 would be approved based on DV2015 approval rate - 834 cases.
The derivative rate grows a little during the year (babies, and marriage) - so the 834 cases would need at least 1400 visas for everyone to be happy.
The quota is around 800.
