"abnormal" appears to be associated mostly with a deviation from the norm that is detrimental or undesirable.
Is there a word for when the deviation is in the opposite direction?
Edit - some definitions, implying negativity:
Google / Oxford dict:
deviating from what is normal or usual, typically in a way that is undesirable or worrying.
different from what is usual or average, especially in a way that is bad
deviating from the normal or average
a person with abnormal [=exceptional] strength
abnormal powers of concentration
often : unusual in an unwelcome or problematic way
I also found two that are neutral:
not normal, average, typical, or usual; deviating from a standard
Not typical, usual, or regular; not normal; deviant
From my experience of communicating with people, I am under the impression it is generally taken in a negative context too. To me an explicitly negative version would be "subnormal", so I am wondering if there is a word that specifies that it is above normal.
