True.
IMHO, it is a different type of power even if the intensity level is the same.
Using a wrong type of power even with the same intensity will produce low efficeincy or low effectiveness.
By the time the grapper get close to the range within the shoulder and elbow,
almost most of the striker who without the grappling training was force into dealing with an unfamiliar type of power flow with low effectiveness.
By the time the grapper get contact the striker's body the striker left with only low effectiveness struggling which fall prey to the unknown un familiar situation.
How can one even dream to win in this type of situation? Cant.
Thus, some go learn grapping, and that is good, because that train one to be able to handle the situation.
It is anything wrong with this? Nope, in fact it is perfectly proper. However, is this still WCK? Nope, certainly no longer it.
As an analogy, to race two cars, one needs to know if both enginees could be par : interm of generating x amount of horse power, and rate of acceleration....etc.
If at this level it is a 30 /70 then the racer needs +20 from the skill to just compensate the weakness. and that means even just to par, one needs to have 20+ more skill. To win one will need even more.
So, it is obvious if the power platform is 30/70 in the elbow to body contact range, the skill is 20/80 in the elbow to body contact range... what is the chance to win?
For me, dont do it because it is a guarentee screw up.
Sure, people then come up with different type of tricks move this and that trying to explain away the weakness. however, that 30/70 cant be explain away disregards how one can demo or show it to one's students. because it is a conditional stuffs and the condiftion might not even exist in the real life contact.
Now, if the power generation compare the two is 50/50 to support oneself differently in the particular range, and the skill of the individual is 30/70 then there still a chance of par and even slight change of winning.
So, it is not time frame, IMHO, it is power generation frame. basically what is the accerelation in the evoke of power to support a specific style of technics.
As we all heard, WCK is famous on its Keng Geng or Fast accerelated Power, it goes as far as any part of the body while get into contact can generate those type of power. Now, without those type of power platform. There is no different between BJJ punch, TDK punch and WCK punch; and how can that type of punch or strike become effective in close range?
using a wrong type of motor/gear to drive a mis fit drill head is just looking for damage. even worse if one drop it harder or thinking the same amount of power will do the same job.
It is time to wake up to face reality.
Just some thought.
