The initial thought was to develop counter techniques against all the other Martial Arts could be interpreted as counterproductive to simplicity!
Think about an engineering project taking body parts that each have a certain motion preinstalled in it, for example, just a wrist that is constantly rotating inward, a fist, that is constantly opening and closing, a foot that is constantly stretching its toes upward to protrude the heel, a foot that is lunging and landing forty five degree toes pointed outward...
Drawing Arts is basically programming a student to become a drawing printer, and Pure Krav Maga is basically programming the student to become a human fighting machine! You really need to learn a lot of skills to do either one.
Well Krav Maga is not as hard as drawing! Apparently many people are using their bodies to walk, run, jump, lunge, squat, roll, grab and hit or kick. People have a driver's license which indicates that they can hit the brake pedal on time to avoid an accident or hitting someone, all done through daily pressure test like environment in the rush hours of thousands of cars all rushing into work.
Basically in a way, Pure Krav Maga Training Seminars, Courses, and Sessions, Workshops, are virtual engineering project. You are the project, and your Instructor is the technician/ engineer! Your instructor has about average half an hour to 45 minutes to test your body prior to any work done. There is no point to start work on parts that might break. Preparation for a paint job, lubrication of rusted bolts and nuts - that rings a bell somewhere...The warm up of course!
Then you have about 20 hours to install the software, of the combat motion, and tactical navigation, test the machine, and reinstall as many times as necessary until you are happy and your instructor is happy.
How is Pure Krav Maga Simple then? If you take Imrich Lichtenfeld and Albert Einstein, you could both categorize it as Genii! Both could be considered as working against the main stream at their time, and both did so out of necessity using logic and unique imagination to arrive at the knowledge they were seeking for.
Simplicity is relative then! And Pure Krav Maga is indeed follow up science. As an Israel Defense Force Krav Maga Chief Instructor, you have the opportunity to observe thousands of male and female soldiers. You input the date you desire into them by giving them instructions what to do, programming their minds and body, and then put them into sparring drills. That is done already after you have mastered several martial arts, and some of your prospective students have already mastered additional martial arts.
And although you do not get paid much, you are not in a position to push for the wrong conclusion. You are truly interested in the effectiveness and efficiency of your training system...(Unless you reach a level of plateau, but not after developing a clear curriculum, and training someone how to teach it to get the full meaning out of it...
I am not into high math formula, but rather into analytics. Will present that as the analytical quality test to Pure Krav Maga as the way it was formulated was not exactly put into detailed research writing in the past. It was more of a tangible fitness department category, then academics physics department.
It just happened that the mastermind of Pure Krav Maga created something that withstands the natural laws of the universe when it applies to human combatives.
The simple thought that first you have to think what is the most efficient form of attack possible throughout the ranges, and devising counter techniques to it, will give you a realistic virtual programming and skills that can be used against any type of attack - the most efficient and the least efficient.
