I was wondering if you could expend on that.
The reason I ask is that I am interested in 15th century Ringen and in the manuscript I am studying there are strikes called "murder-strike". The idea is to strike or press as you move forward some particularly sensitive area of the body. It is bigger area than what we would cover now by pressure points. (But it can be use to press or to strike). And I was wondering if you were refereeing to something similar.
The simple answer is - trying to affect someone by simply striking them is.... well, a hit or miss proposition, if you'll forgive the pun. The old ways had to do with understanding how a strike to a vulnerable area would disable in a specific way, be it a nerve point, meridian point, plexis, soft tissue, muscle, joint.... striking any of these will result in different results to the attacker.
You can see the beginning of this in the basic Daito ryu response to yokomen uchi ikkajo (ikkyo.) The first response is both a connection to the strike, and also a strike to the nerve point under the attacker's elbow.
