In some guy's opinion the steps you mention are unnecessary. Totally unnecessary. This guy never did a single defat in his life, freeze-precip and re-x were his weapons if pure clean spice was required.
I think you should just start playing around instead of reading every tek word by word. Then you'll appreciate which are the really important steps and which are totally redundant. And allow yourself to fuck up a few things, mistakes are really big teachers, maybe better teachers than any advice one can give you in any forum
