Yes, I read DraX's tutorial. Unfortunately, it suffers from the same problem that many do. The guy knows his stuff, but he writes the tutorial from the standpoint of someone who already knows it. The tutorial wanders around at times, and is quite confusing. In fact I wonder if he tried to pretend he were a beginner who needed step by step instructions. I was thinking there should be some sort of "strip delta" program freely available. All we'd need to do is click on a button, and the work would be done for us.
