Current CRS trend

My current CRS score in my Express Entry profile is 431. I had submitted my profile a few months back.
I have been reading online that currently at times the application getting picked have a CRS score as low as 380 or so.
What could be the reason that my application is still not getting picked?

I am not aware of any such trend where one specific application is left out.

Infact, i have not seen any invites with 380 points.
