Oh you've got the instructions, all right. But just like Wazoo's, nobody knows what they are. My aim is that when I get done beginners understand and use the technique. I don't bring any special knowledge to the process at all, and anyone who thinks I do is mistaken. I specialize in instruction and techniques for beginners in manual targeting. What I bring is an ability to communicate to beginners at a level where they understand what to do and understand the process well enough to reason for themselves that my instructions are valid. THEN they can introduce wrinkles of their own, refine the process for more precision, adapt for angles other than 45º and 90º, and whatever else. But that's more advanced stuff. I'm building confidence that they are capable of manual targeting. Only confidence allows you to go forward and perfect your skill.
I am more a translator than a theoretician. OK, I'm a cheerleader too.
My stock in trade is language, not the science behind the attack techniques. That's YOUR specialty and without you and several others I would have done NONE of this.
