'standardly-adjusted' originates from the combination of 'standardly' and 'adjusted', where 'standardly' refers to 'in a standard manner' and 'adjusted' means 'altered or moved to achieve a desired fit or condition'.

'standardly-adjusted' evolved from the need to describe processes or data that have been modified to meet a specific standard or norm.

Initially, it meant 'modified to meet a standard', and this meaning has largely remained the same in modern usage.
