>Right, I understand. The point is - I have complex input and trying to produce the same output. It is not easy. I also try to make the methods small. This is not simple and requires several iterations.

A rule of thumb I like is that if a method if more than a screenful of code, it's too long. That's 15-20 lines of code. There is a term for methods longer than that: POOP (procedural object oriented programming). Break it down into small methods relentlessly.
