why is CSAT result published so late? an analysis

Has anyone ever wondered why it takes sooo long to generate a merit list after CSAT??? M sure each one of us has... Cursing UPSC each moment... What are these guys up to?? After all we know that our papers will be checked by a computer... Assuming 5 lakh candidates , so five lakh papers... Assume the maximum time taken to reach correction centre after the exam is 10 days... Computer checks say at 0.01 secs per question... 180 questions, so 1.8 seconds ... For 5 lakh papers it is 250 hours.. that is approximately , 11 days...  Giving a little tolerance , assume it to be 15 days... Now these results need to be compiled at a central place. 5 more days.. Now the interesting part. Deciding on the cutoffs... The entire data is analysed and a certain percentage of students is selected which gives a cutoff. Each copy now needs to be marked pass or fail against the corresponding roll number. Hardly 5 days. The next part is uploading... 2 days... Adding the above we get a grand total of 37 days... Giving a little tolerance we assume 40 days... UPSC takes more than 60!! Think about it... Either the computers are slow or something else is cooking up there in the Raisina hills.....
