When should I NOT send a low test score - even to state flagship schools?

I noticed the current Fall 2022 freshman profile here:

https://www.colorado.edu/oda/sites/default/files/attached-files/firstyearprofilefall22.pdf

Shows average SAT as 1273 and GPA 3.72.

Also based on advice earlier above in August for IU,
see CDS of UC Boulder’sclass of 2025, your score is still below 1180 , 25th percentile and only 32% submitted scores.
So, imo, don’t submit scores would be consistent advice.
