No because if Tc is cast at J and if J is compressed with K then K is compressed with J so itīs relevant where time is sucked.
That's what I said: in a finite line, having a referencial point(namely the point where TC is cast) is relevant, ALL UNTIL TC IS COMPLETE because when that happens, the referencial point is the same point as every other point in time.

As for the rest of this point, you must have misunderstood me, or gotten confused. I have always said that TC combines all era into one era, not that you delete all times but the referencial point. And no one brought up "space compression" either...

To create TC instantaneously is the same as to made it progress with infinite velocity isnt it?
Yes.

Sad Ultimecia hadnīt realized she canīt complete TC with finite speed.She is really stupid.(Or maybe not).
She CAN complete it if the line of time is a finite line. However, since we don't know if it is finite or infinite, and there's no way of knowing either, it's pointless to call her stupid or not.

This is exactly the final conclusion.
Axiom1-Ultimecia wanna to compress all time.
Conclusion1-FF8 world is time compressed.
Conclusion2(or conclusion of conclusion)-Seed can also live on TC along with human beings.

Axiom2-Only Ultimecia can live on TC
Conclusion1:FF8 world is not time compressed.
Conclusion2(or conclusion of conclusion 1):Ultimecia cannot compress all times

So either Axiom 1 is thruth or Axiom 2 is thruth .Not both.
Well, clearly Axiom 2 is correct here, since the game tells us quite specifically that no one but Ultimecia can live in TC. But your conclusion 2 in Axiom 2 isn't correct. The correct conclusion would be:

Ultimecia is not able to compress time.
