You don't get it.
You're hopelessly confused.
When the travelling twin returns, he has done the FULL TRIP, not half of it. He has gone the total distance for the trip (whatever that happens to be measured as in any particular reference frame).
I am not resdponsible for your failure to maintain continuity of physics. It is becaue you are exercising "DoubleThink":

Doublethink means the power of holding two contradictory beliefs in one's mind simultaneously, and accepting both of them. The Party intellectual knows in which direction his memories must be altered; he therefore knows that he is playing tricks with reality; but by the exercise of doublethink he also satisfies himself that reality is not violated. The process has to be conscious, or it would not be carried out with sufficient precision, but it also has to be unconscious, or it would bring with it a feeling of falsity and hence of guilt.
Doublethink lies at the very heart of Ingsoc, since the essential act of the Party is to use conscious deception while retaining the firmness of purpose that goes with complete honesty. To tell deliberate lies while genuinely believing them and to forget any fact that has become inconvenient, and then, when it becomes necessary again, to draw it back from oblivion for just so long as it is needed, to deny the existence of objective reality and all the while to take account of the reality which one denies - all this is indispensably necessary. Even in using the word doublethink it is necessary to exercise doublethink. For by using the word one admits that one is tampering with reality; by a fresh act of doublethink one erases this knowledge; and so on indefinitely, with the lie always one leap ahead of the truth. Ultimately it is by means of doublethink that the Party has been able - and may, for all we know, continue to be able for thousands of years - to arrest the course of history...
So you're claiming that, regardless of whatever the travelling clock is doing, the resting clock measures half the time it should for a particular trip.
You're off with the pixies.
See above then reconsider the physics facts.
If you drive half the distance in one half the time of full distance then your clock has not dilated - PERIOD. If you clock has not dilated then it ticks in sync with the resting clock and upon arrival both clock display thecsame accumulated time.
Since that is not in agreement with empirical data that component of SR is falsified.
Time dilation is real but it ONLY requires a dilated clock NOT distance contraction. Does this require a bit of adjustment to our thoughts about physics. You bet but those adjustments are far more rational than SR.
Now get off your high horse and denial fit and address this simple physics and math fact:
Where TT is Traveling Twin and RT is Resting Twin
......____TT___..._RT_
v = 0.5d / 0.5t = d / t.
Put into english without all the excess text as relates to the twin paradox and claims by SR, it says.
The traveling twin and resting twin clocks both must read the same when the traveling twin returns home.
This proves your arguement is physically false.
