No. It simply means to fix a distance.
Hmm, I've never come across anything like that as a definition of kime before…
"Kime" (決め) comes from "kimeru", and basically means "to decide" (Judo's Kime no Kata are the "forms of decision/decisive action")… I suppose it could be applied to deciding upon/fixing a distance… but again, not something I've ever come across before.
There shouldn't be any tension because there is no opposed muscles working against each other. "Braking, while under power".
Kime is often used to refer to "focus, precision (of action), a decisive movement", and the "snapping" of the gi is often seen as an indication of proper kime… as in many (most) arts, this is achieved by a sudden application of tension throughout the striking limb at the moment of impact… so there should absolutely be tension at that point (just not in the surrounding moments). In sword arts, we refer to this as te no uchi (pretty literally: inside the hands), and it's essential if you want to be able to transfer power without losing your weapon. In unarmed striking arts, it's a similar idea… the tension is to transfer power while not damaging yourself at the same time.
With regard to striking, tension can only happen when you have opposing muscle or tendon groups both contracting at the same time. Tension = Tug of war.
Well, yeah, that's how tension is achieved in the body… that doesn't mean that it isn't applied…
Kime is to mentally decide or establish a set distance where your fist will stop.
Er… huh? No, that's not the way that the term is applied at all… the closest is that some systems use the term "kime" to refer to specific targeting (kyusho)….
You have to learn through striking how to actually hit that specific spot.
Which is about targeting, not distance… of course, if your distance is off, your targeting will be as well, but they're still two separate concepts.
Done correctly group a muscles/tendons explosively cause the fist to travel to that target. But precisely an instant before arriving at the point past the set distance all Group A drivers disengage and cease power.
A fraction of that instant is total relaxation of group A. While at the same time a different group engages. Group B does not fight group A.
That would be tension.
Honestly, I think you have that backwards… during the execution of the strike, you have one group of muscles driving the strike forward, without opposition from the opposing group (otherwise you're too tense during the strike, which will rob it of power, speed, and more), with tension being applied on impact to avoid your striking hand crumpling and injuring yourself. Being tense during, and relaxed on impact would result in kinda the opposite of an ideal strike…
When firing a strike into empty air.... group B is responsible for counteracting Inertial Forces caused by the punch.
Primarily to maintain balance, poise and structure.
When striking a solid target, power group B is for sinking the energy into the target without letting the strike become a push.
I don't quite follow what you're meaning by "Group A" and "Group B" here… can you give anatomically accurate examples? Cause this doesn't seem to quite make sense to me…
Punch retraction serves a number of functions.
I wont dive into punch retraction here…
Okay.
But whether you want to send the energy the distance from the target's cheekbone to the back of his skull... or if you only want to send the energy only a few inches deep you will have to set a distance. (Kime) either way.
Er… okay… kime as in focus, sure…
Elbows are moved one direction by the biceps and the opposite by the triceps. Now kime shouldn't be about using one set in opposition to the other. Ever.

Again, I'm going to say that this is not the common application of the term "Kime"… yes, tension is commonly a part of kime… which can (and often does) involve muscle groups working against each other… so… gonna disagree again.
Every type muscle provides power by means of contraction.
But not all contractions are tension.
Getting a bit into semantics, but okay…
There are two methods of muscle contraction or said another way... muscle contractions can be described based on two variables: length and tension.
Doing bicep curls is using elongation/delongation. Or muscle length.
Not really sure what this has to do with much, honestly… I mean, you start off by saying that kime refers to "setting distance" (again, I've never come across that as a definition or application of the term at all), then talk about muscle groups and tension (which is closer to the actual application of the term)… taking it to how muscles work in bicep curls. For the record, there can be plenty of kime in things like bicep curls, though…
But the thing that really got me reading (and answering) this thread is the following (and all other related posts):
Yeah, well once one learns & trains real TMA, then one can criticize, competently.
ShotoNoob.
I've watched your posts since you came along here… and I'm going to say this bluntly.
You have no idea of what traditional martial arts are. You have your own perspective, which is skewed and highly inaccurate. Your idea of "real TMA" is highly suspect… and this is coming from someone who trains (and teaches) arts far more "traditional" than anything you've ever dealt with. Trust me on that. Your posts are so littered with false beliefs and dramatic condescension towards everyone else's training that it borders on trolling… or pure delusion.
Good luck with that.
