I disclose this secret why many applications in Sep 2015 was prolonged. You konw about 500 applicants had been nominated before January 2016, the mean nomination time is about 2-3 months. Normally the normination time should be about five to six months. As we see, many application in January, 2016 had been nominated after May. Their mean nomination time is about five months. However, in order to prolong the mean time of September, 2015, they had to lay aside many applications, especially ID from 550 to 770, for more than three months after IP status to balance the mean nornimation time. During this time, small number of applications ID between 770-1100 had been normiated in a norma way. So this is the reason why some early applicants are only processed after June. I guess all Sep applicants should be normiated before September, 2016. Ok, the mean time should be about 5 to 6 months. How do you think this? ;D
