Pretty much all the performance-related incidents and accidents I’ve seen have been due to getting the calculations wrong. This a good place to apply rigour if you’re going to apply it anywhere.
Given that most civil operators use software that minimises engine wear in exchange for runway used, and take advantage of ATM and fixed derates, it would be hard to discriminate by timing between a correct thrust setting and not. If you are achieving the right N1 you are almost certainly getting the thrust you want - the secret is to make sure the the numbers makes sense: MTOW and 70%N1 probably won’t cut it.
I suspect on most types there is too much of a spread between the time to a certain speed on a short runway (or intersection departure) and a long troll down 4,000m with a low flap setting and an overspeed takeoff to have a figure in mind on a stopwatch. There’s a lot more latitude to reject at low speed (<80kts) if you don’t like what you’re feeling but you have to be a bit more rule based at the higher speed end.
