Sorry for getting you wrong. Alright, maybe it'd be a training for you and there's a chance you'll learn something from it. For me it still sounds like a lot of pointless work though. Well, maybe I shouldn't talk about pointless work after confessing that I used to delete most of my SP levels myself, you can ignore me, but imo it's something different - thanks to my mistakes I try to slowly form a style - you won't learn that from redrawing levels, you can only start to adapt their own style and so you might eventually lose a useful ability of thinking outside the box. I just can't imagine myself, working like a machine in the way you described. No creativity involved. But oh well, I really don't want to interfere with your choice, just go your way and I will go mine, let's see who reaches the goal first.
