Sorry, I'm not sure I understand the reasoning behind your last sentence.The response rate varies by country. Nepal had a very high response rate and very little backlog (good agents).
Now, what many people have missed is the change in the blend between Iran and Nepal.
First point is that Iran has a higher derivative rate than Nepal.
In 2014 Iran had more entries than Nepal (545k versus 380k). In 2015, Iran entries dropped to 499k but Nepal increased to 545k.
What does that mean - well it the derivative rate means that at the same number of family (~5000) Nepal would have more cases than Iran. The entry rate means that Nepal would have received more cases per thousand also. So - Iran actually cuts off sooner than Nepal BUT the Nepalese cases are more dense.
So - Nepal cases are more dense this year and each Nepalese case has a higher response rate and an extremely high approval rate. SO - that means they will hit their limit faster and it has the effect of reducing the highest case number. Hitting 13350 again has always looked doubtful to me once I saw the entry data (just a couple of months ago).
That means that although Iran AP cases are still they key to the whole thing, there is little liklihood of seeing 13XXX, no matter how bad Iranian AP cases do....
I guess the slow progress of Asia made it doubtful that we will see a high final, although that's logical thing.
