Lol. You are the extreme Bear here and I am the Bull!That is a good joke.
There will always be plenty people just a bit below CRS or those that do not have CBL 9 in all skills so they will be redoing the IELTS test.
Your personal choice can be called Penny wise pound foolish. You do not know what will be the exact behaviour of CRS score in the future. You do not even know if there will be some last minute changes (like the additional points for French last year). On the other hand every day whole EE gets bigger with more competition.
So it is better to overkill with your score (to have eg. 450+), than waiting for it to drop (some do not have much other choice if they have already exhausted any quick fixes).
But I think, you can wait and see.
good luck
hope you got me
