CR will never work as anything other than a loose guide until it takes into consideration PC power level, not level.
How else do you balance between a rested 5th level wizard and a 20th level one with no spell slots left and half hit points?
Or an optimised hexblade/paladin vs a same level monk/wizard built for RP?
And then you need to take into consideration player and DM tactics.
Like, seriously. What do people expect?
