Very intersting subject.
I have been very interested in performance for many years, T/O and LDNG performance is so interesting.
We have seen so many examples of getting it wrong on T/O and LDNG, I guess many many get un-reported to a greater or lesser extent.
I used to think an easy "rule of thumb" chart could be used to help/assist in helping/informing/assisting to avoid falling into traps, I guess it can be of help, but history records it has limited use/effect.
I list a a few examples of classic events that may of been helped/avoided if a system was in place to remove/reduce/reduce-effect them, see below.
Air Florida, EK at MEL, SQ at AKL etc etc.
As the previous and so many un-mentioned events show that operating pilots can't see the big picture of performance/power/thrust/EPR/N1/availabe runway lenght/distance avail etc etc.
So many systems avail to help assist this prob, but cure could be less safe overall.
Reminds me of also runways not in use and reduced runways problems.
