Yes, I have. I served in the Army and have more then my fair share of dust on my boots.Ever shoot a moving target, the speed of the bullet doesn't matter its the timing for when you pull the trigger that lets the target move into the path of the bullet.
A jab executed without timing ain't going to anything specificly because its like shooting a moving target target and trying to either spray & pray (hoping to get lucky) or trying to catch the target.
Now a jab can be effective I not arguing that but you have different types of jabs; a jab & hard jab. A hard jab, also called a hard lead, involves stepping forward behind the strike; exactly as my first mentioned. Usually a jab is used to either prob for a weakness or to offset the opponent's timing. If an opponent steps forward to strike & catch him with a jab (that requires timing) & if he steps forward and I meet him by steping forward with a jab (making it a hard jab/hard lead) my jab is slightly slower but far more powerful.
Well I have to disagree with you, speed is not the answer here proper technique is and in the context of proper technique, speed is one thing, but speed alone is not. Power comes from more then simple speed, it also involves timing, distance & stability all of which effect something like marksmanship as well; if you don't a stable firing platform the round is less likely to travel a straight line, if you don't understand how distance effects timing (especially against a moving target) & time your shots accordingly the speed of bullet is irrelevant.
Once again you are arguing a straw man argument. That's fine. If you don't want to accept the math for what it is, that's fine. It is really simple physics. I'll repeat my self one last time in the hopes that you finally get what I'm saying.
Repeat number one: I agree that timing is an important part of fighting and is crucial to making a strike effective. However, effective and powerful are not synonymous here. Not all powerful strikes are effective for the situation, and not all effective (for the situation) strikes are powerful strikes. We are talking about the measurable power of a jab here, not what makes a person an effective striker. See the difference?
Repeat number two: Velocity is exponentially more important to the power of the strike then mass behind the strike. That is scientific fact. You can argue that till your blue in the face, it won't change. And it is the entire basis of my assertion. In fact it was my entire point. The Jab has real power because of speed and transfer of energy. Where as you said, and I quote:
...a jab is a probing strike with no real power just speed. The jab wouldn't have hurt much if at all because it lacked the mass of the body behind the strike.
Speed is more important to power then mass. More important then either is the transfer of the the kinetic energy. (there I've now repeated that three or four times now). That was the entire point!!!! You then started talking about timing to distract everyone including you and me from the very real fact that you misspoke. Your original statement, to which I have been addressing this entire time does not hold water. It is that simple. I have math and physics to prove it, you have offered nothing in return to substantiate that mass is more important then velocity regarding the power of a strike. Mostly because the math doesn't back it. Perhaps you are confused and can't articulate what you really mean? Right now, I'm inclined to believe that since you keep talking about things I have either already agreed with you on that are irrelevant to the original point.
Repeat number three: Velocity is measured by time it takes to move from point A to point B and has nothing to do with timing. It is separate in this context.
Repeat number four: Another key element of power is the transfer of energy. A slower punch may hit harder because the transfer is better (though if the transfer method stayed the same and the velocity increased, the power generated would quadruple). This is where proper technique comes in. Technique alone = Power. Speed plus Technique = Devastating Power.
You can argue that timing is part of technique all you want, and outside of this context, I'd agree with you. But the simple physics measures power in following way:
Kinetic energy = 1/2 mass x velocity^2
Momentum = mass x velocity
There is nothing in that equation regarding timing.
You are a good shot and can use the weapon well because of timing. However, that does not affect the fact that every time you fire it, the fps is the same. The velocity of the ammunition, the stopping/penetration power is and always will be separate from the timing of the shot.
The initial argument assumes proper technique, but even if two poorly executed jabs are done with the same rate of transfer, the one with more velocity will be measurably more powerful!
Once again, I never was saying that timing is irrelevant to a warrior, only that it is irrelevant in the context of this conversation about what makes a punch powerful (not effective). The only measurable means by which we have to calculate the power of a strike, is by measuring the the variables above.
