I just made these calculations from available data on the accuracy of estimated percentage of users in the spreadsheets vs total number of applicants.
In 2013,
NOC 2173 ~ 28%
NOC 2174 ~ 31%
NOC 1112 ~ 19.67%
Now from 2014 spreadsheets, calculating the number of people who recorded an entry for PERs received(or their application is now in stage above PER) vs the updated data on CIC website, it looks like
NOC 2173 ~ 24%
NOC 2174 ~ 26%
NOC 1112 ~ 16%
So I guess the estimates are not too bad, percentage error may not be more than 20% in the estimated figures. Feel free to comment.
