Except for pointing out the detailed colors of how the training environment does not match all of possible real scenario environment and getting hung on that, or getting the reader in agreement with it which might be a good opener, the major points that Reality Based Training deals with is how to convince your mind that it is in danger while in training and also to ensure you can convince your mind it is in danger when you are in fact in danger in real life and the adrenal state which is naturally triggered by danger.
It's not important if you are dressed in a Gi, topless, Street Clothes, Commando Fatigue, or Designer’s outfit. It does not matter whether or not you are using the comfort and luxury of a training studio learning how to fall on soft mats and using a safe technique step by step teaching you how to fall and roll safely on a concrete floor.
The key is to learn principles of body motion and reaction through learning techniques that will work in unsafe environments.
I think you get that adrenal state when you spar, but through the training you train in a fashion that subject yourself to incremental danger. Well when you face a scenario in the street from my experience, if it does not happen immediately, and you need to wait a little longer because you are trying to avoid a fight and keep your composure you can feel your pulse getting heavier and you ask yourself what the fuck with all my Krav Maga training is this happening do I have a natural fear?

So your body does react to anything and might give you uncomfortable sensations, but it should not slow down your reaction.
If you keep in your mind that if the opponent starts to run at you trying to kick you, your training and your determination would propel your body to lunge and kick him before and continue to use your arms as needed.
In the shorter range if you got hit it is not because your adrenal state slowed you down but because you let a person get close to you to the point where your reaction time is not sufficient. While you feel your pulse getting up as an aggressor is trying to intimidate you, you have to cover the basics at the same time. Be determined to response to a threat according to the distance.
The starting point is awareness when you see an unusual motion or activity of humans that could pose a threat, assess the danger that the threat poses, then when you feel it is directed at you or other innocent bystanders, assess the timing required to responsd before it is too late for you to defend yourself or to rescue others from harm, and then keep in mind the engagement range options.
For example if a person is moving fast toward you with anger verbally abusing you, extend your arm and shoulder pointing to the ground few feet in front of you and and tell him to stop right there.
Most cases this works, and if he keeps moving you lunge a kick and continue with hands as needed. If he walking slowly to you in a bar with the intention of intimidating you and perhaps starting with shoving you, you extend your hand and shoulder fingers touching his throat and tell him don’t get any closer to me.
If he is still in motion, you grab his throat and hold him like a chicken. If he is trying to take your hands of his throat for his sake he does it right otherwise he would be helping your to pluck his own throat. If it gets to get a hold on his throat you do apply sufficient pressure to lift him off his heels. If he deflects your hand, you counter his deflection with your own and counter attack him with impact punches, elbows or plucking soft pressure points or throws with neck leverage if needed.
Since you are in a ready state and he is in intimidating state where he is not expecting you to do this, if he reacts to your control of the situation he will usually be one step behind. First he feels intimidated by the unexpected move you produced.
Then it is the psychological advantage of the reversal of fortunes. It is all about speed of motion while entering the dangerous zone. If the speed is slow and the attacker is walking closer without lifting his knee for a kick, the engagement range would be a distance of an arm and a shoulder.
If the attacker would then still try to kick, you will use your body to escape the kick if needed to, or if the distance is even closer, you will use your hands to hit him in the face or groin before he was able to complete the kick.
If someone managed to grab your clothes, wrists, head, neck, leg, etc, you will move close to him or change direction to avoid the pull of push force and reach for a pressure point in the neck or head area or the groin area.
