What people need to understand is regardless of the X number of NEW entrants in the EE pool between draws, the distribution of EE profile scores cannot be assumed to be normal. Few factors can increase scores such as language tests, years of experience, obtaining higher degrees, however as one can observe, these factors are time-consuming for the most part. It is easier to lose points (changing civil status, growing older (29+).
In addition language test performance tends to remain fairly stable over time. When retaking tests, improvements if any are only marginal. The marginal differences can mean shifting to a higher proficiency level for some, but this will apply to a few profiles relative to the total number of active profiles.
So with each decreasing point, the number of EE profiles increase, by how much, nobody knows except IRCC. Therefore the distribution is more than likely positively skewed. Let's say for the sake of argument there are 1000 profiles with 430, 1500 at 429 and 2300 at 428 and 5000 at 427, it is obvious that IRCC will not go past a certain threshold because say a draw is held with cutoff of 428, EVERYBODY with scores above 428 PLUS all the 2300 profiles (in the example) with 428 points will need to be invited and this is just unrealistic since 1) it will make PNP's avoidable by applicants *i.e. no money for provinces*; 2) the "quality" of future of immigrants will be "too low" to accomodate for all of them without possible straining the resources of the country and also to avoid setbacks and significant burden which may be experienced by new immigrants (like it or not, immigration services rate prospective applicants on factors likely to affect successful settlement in the country, take the medical exam as an example); 3) the quotas of immigrants will be reached too quickly and they will have to replan and rethink intakes, frequency, quotas, etc at the federal level.
Let me stress that I am in no way wanting to crush people's hopes, but instead I just want to help people having realistic expectations and hopes regarding the process. I know I will get many more -1 but so be it.
Good luck to everyone of you.
