This has been raised before but nobody commented on it. It's about the "Estimated date by which you should file your application to be in the cap" field in the spreadsheet.
A couple of forum members including me think that this field is not calculated correctly, and that it may mislead applicants who are still preparing their applications, and make them feel more relaxed about time than what they actually should be.
Take for example NOC 2174. At the time of writing this post, 278 applications have been received and logged in the spreadsheet. Since 31% of applicants worldwide log their names in the spreadsheet (based on actual FSW2013 figures), this means that the total number of worldwide applicants who have submitted their applications under this NOC up to date is 278 / 0.31 = 897. Since 86.92% of applications pass the completeness check and count towards the cap (based on actual FSW2013 figures), 897 * 0.8692 = 780 applications are submitted and will be accepted by CIC for this NOC until today.
Now, about 72 working days have passed since May 1st, 2014, which means that CIC receives 780 / 72 = 10.83 (valid) (complete) (acceptable) (counting towards cap) applications every working day for this NOC. With (1000 - 780) = 220 applications left towards cap, and with 10.83 good applications received per working day, we still have only 220 / 10.83 = 20 working days until this cap is reached. This means that the cap will be reached on September 7th, 2014. How come the spreadsheet says that the estimated date for cap closure is December 16th?
