The Boeing and FAA training material is very general. (Trying to keep it simple.) It really addresses the max weight scenario.
I think in a way it's done the aviation community a disservice to some degree. Many pilots are now in a "above 80 kts., I'm going" mindset.
In a great number of cases, we have much more runway than is required to accel-stop. There's nothing inherently dangerous in stopping an airplane from 130 kts or so, we do it on every landing.
Except for extreme weight or density altitude situations, most transport caregory airplanes achieve 120 kts about 3000' into the t/o roll. (Look for it, you'll see.) Now, if I'm on a 10,000 foot runway and I've got 120 kts at 3000, I've got 7000 left in which to get it stopped. NO WAY I'M TAKING THAT FIRE WARNING INTO THE AIR! At 80 knots I've only used about 2000' of the runway.
Even in a balanced field situation, I'd rather go into the mud a little bit at the far end than take a fire with me flying.
These airplanes stop much better than most pilots give them credit for. That's because most have never done a max effort braking stop. If you ever do, you'll know what I mean.
In the words of a wise old pilot, "The weak pilot thinks about the takeoff. The professionals think about the abort. EVERY SINGLE TIME."
