Yes anything can happen really. I know people like to use their historical facts to form future predictions but nobody really knows what's going to happen until after it happens unless they work directly for IRCC. I've noticed that there are people in here quoting facts as if they're 100% sure when they're not and will only seek to justify or find a reason for the anomaly after it occurs because they had no clue it was coming. Nothing wrong with trying to make predictions as it's very helpful to some but I'm sticking with encouragement. If someone has a low score and there's something they can do to improve it, they should definitely tey their best to improve but in the mean time, some hope wouldn't hurt.
413 at the current state of EE, CRS point system and the yearly quota is not really a prediction, but a wishful thinking.
Last year listening to similar wishful thinking cost some people chance to get ITA (some did wait too long to retake their IELTS, others did not accept NOI from Ontario. And all of them were thinking that score would drop to whatever happened in 2017.
Unfortunately those presented ugly facts are much more accurate, as they are using all available data and estimations coming from them (for example steady increase of total EE profiles is a fact, that you can compare checking data from 2016 and 2017 with the current status).
The only way to change current trend and balance would be to throw system out of balance. So for example sudden heavy increase of yearly quota, would result in decrease of CRS.
Also a redesign of point system can put the balance demand to the different number (higher or lower) however that would say nothing about how easy can one achieve such score. And lastly a change in Canada attractiveness may change this score (as that will directly influence how big the competition is).
