For all I understood, then we don't know a fuc.... thing what is better over the other, while one say it was not significant, then one understand that it is Ok or almost the same, while apples to apples where not compared.
Key words you use, model would suggest, sometimes, assume, probably, probability.
And statistics had been proved not to be 100% accurate.
Non of them translate to FACT.
We still don't know facts and probably will never know, as no sane group of divers scientifically proved similar individuals will offer them self to play lottery with DSC, to much money to much risk, we still are wandering in grey waters.
We can use one algorithm with success as well as a mix but you still can get DSC, but at least one try to follow the Algorithm and mix choices that had less incidents and learn from others bad experiences, that is part of self preservation, it will be kind of stupid to go in the opposite direction, because of maybes, assumptions, probabilities.
You cross a river using 2x2 timbers and it had broken 5 times in 20 crossings, then you find 4x4 timbers and it broke 1 time in 20 crossings, what does your common sense tell you which one is better over the other and what will be your preferred choice ???
