They are not just “gazing at them”. They actively change “k” factors in the model to try to get them to fit what they think they should do. That is how these models work. There are so many factors that we cannot accurately measure, that they just assume a number, then try it. If it doesn’t give them what they want, they substitute another number. It is GIGO..Garbage In, Garbage Out.
So I guess nature is impossible to understand and science is worthless.
