Everyone here talking blindly about ITAs (numbers, trends) and potential implication on immigration targets come across as hugely uninformed and completely unaware of how organizations work.
Remember that Canadian immigration programs have a larger mandate to achieve - to attract and retain the most talented individuals in the world - and - to maintain Canada's relatively high standards of living and image as a nation of immigrants.
This objective is more important than an immigration target which represents sub 1% fraction of Canadian population.
The immigration agency also has far more info than any of us. If there are indications that individuals below a certain threshold are not likely to improve overall quality of life for the remaining Canadians, they will not be invited - at least not in the Express entry system. There are other avenues for those people. For now, through EE, the CRS score is highly correlated with how Canada measures individuals.
In light of this - if I headed the immigration agency - I would look through data and cleverly manage different draws to ensure CRS stays up and trends higher year over year while staying close to immigration targets.
That's exactly whats happening today.
How does this impact an applicant?
It should bode well that there's a push towards higher scores. Improves chances of Canadian standards being maintained or enhanced.
Don't try to predict when the score will fall. Assume there will be a constant push up with relatively fewer instances of big drops. Focus on getting your maximum score.
Don't push back on the immigration agency or their methods or how stressful the process is. They don't need to have your best interests at heart. That's your country's job. The Canadian agency needs to have a Canadian civilian's interest foremost. They should adjust the program and keep pushing the it towards better talent.
Finally, being an immigrant myself (right now in the US), I can tell you that the Express Entry system is currently the world's most transparent system - this is the best there is. Just look at how other countries manage this process and you'll see that Canada is doing a great job - not just for themselves, but this system truly is the most friendly for any applicant.
TLDR - Stop whining and calculating. Just push towards the best you can be and show that you deserve the ITA.
