You revealed nothing new that wasn't already known pre-mix.
I think you are getting too hung up on doxxic change. It isn't the important part. No one is spending that or claiming it is not deterministically linked. We spend what is being mixed, after it is mixed.
Assume you already know the location of 0.75 bitcoin before a mix. I split 0.25 bitcoin off to the side to park as doxxic change, and the other 0.50 bitcoin goes into the 0.50 pool to mix.
What new information did you gain that wasn't already known? Now point to the postmix 0.50 that is mine that I'm actually going to use (again, im not spending the doxxic change). You can't.
By perfect coinjoin I mean equal amounts on either side + maximum # of interpretations or N*(multiple of N) mix. Why does this matter? Because every given output is exactly as likely to be from a given input as any other. Max uniformity/fungibility = better for privacy:
