That is the distinction of ADHD. Self reflection, the bit about offense, is important because for the person without attention disruption there isn’t a performance difference to reflect upon, but for other people there is an issue of concern.
It has nothing to do with optimizing performance of a task. Doing the laundry for your family for the 10,000th time is a chore, not a task that is optimized.
This is a pretty common thing to do, so I’m not sure why this is so confusing.
