Mechanism of Announcing the number of complete applications per week.

Mechanism of Announcing the number of complete applications per week.
    i am observing cap updates since July 2010, i closely observed cap updating till now.
   Last time NOC 3131 caped in mid march 2011
    In the march no of the applications received increased many times
   My question is if CIC was working on its routine, why number of the applications it received increased many times in March.
   It announced 500 applications till 10 January 2011(in 6 months) but in mid of March it announced cap, remaining 500 applications filled in only 2 months and 10 days.
   if the CIC is working on its routine irrespective of applications reached , and it took about 6 months to announce 500 applications then it should take further 6 months for remaining 500 applications to announce , but actually it did not happened , it took only 2 months to announce remaining applications .
   Therefore the conclusion is that there is a mechanism to announce the complete applications in the CIC which is increased or decreased according to the number of applications received and it is not too away the application receiving date.
   The purpose of updating the number of applications weekly is to facilitate the new applicants as well as CIC itself to reverse the bulk of applications which are ready to post.
   Now a days CIC is receiving 4-5 applications per day of NOC 3131 but you will observe that it will increased in November and may be CIC announce cap in the mid of November .
   It announced 320 applications in 107 days (1st July – 17 October)
   If it is working irrespective of applications received, then it should take 60 days to announce remaining 180 applications.
   But you may observe in coming weeks it will not happened , CIC will not take 60 days , it will take only 20-30 days to announce cap because there is rush of NOC 3131in coming two weeks and CIC mechanism is according to applications received , so it quickly announce the cap in November.
   So back log may be 7 days only.
   God knows better.
