Lots of things affect how long a particular wu takes, not just the number of steps. You may have a very simple molecule with 1000 steps, or a very complex molecule with the same number of steps. Obviously there are a lot more ways a complex molecule can fold, so the process takes much longer...
That's rather rude to ignore my questions.
I almost get the word, but feel that you are just stammering it a bit...
Take a deep breath (whatever you can stand over your stench), relax, and enunciate.
It's alright, we can wait...
