I like your idea of what matter is what the program must do, and thus we must think firstly what will be the functions. I may be wrong, but once we have a 12 parameters function, it may be interesting to factor out to more than one class. If I do this factorisation as a no-brain, I will create a "FooParameter" class with 12 getter and setter. It will be better to stop and think of what will be the easier to read. Ie do some abstraction work: double getDistanceTravelled(Point[] relevedPositions) instead of double getDistanceTravelled(double[] x, double[] y)
