This training method is a good demonstration of what all the other martial arts tend to do and a good demonstration of what they are capable of doing. Therefore it is a good way to make it realistically to Krav Maga students what to expect should he would not timely react according to the Krav Maga principles.
The best way to learn is indeed from experience, but the more you want to learn the more you subject yourself to the risk of injury. If you are being KO’d you usually would not remember how it happened. Therefore you need to break down all the pieces of the puzzle and measure everything you can, put the knowledge in perspective and figure out how the machine operates. At the end you need to test it. But if you have a clue what the answer is going to be you are saving yourself a lot of injury and time wasted.
Taking element of efficiency into account, you need to see when is the use of a kick, a knee kick, a hand strike or an elbow is optimal i.e. in what range and what are all the implications of being in that respective range from a point of reaction time- the time you need to react before you got hit, or the time you are trying to hit before your opponent can block.
Since humans have the capacity to attempt and strike you from the second they can reach you physically, in order to make yourself self defense proof, you need to react at the moment that they can reach you and not a second after that might be too late.
Since generally from the long range it is faster to reach someone with a kick and from the short range it is faster to reach someone with a punch since you do not need to shift your weight on one leg and lift the other (your front hand is closer to your opponent anyway) you need to attack in the most efficient manner and at the same time worry only about the most efficient way the attacker can use to reach one of your pressure points.
