Absolutely.

During the trip, it is impossible for beeps to have been lost, neither

No matter what path through spacetime Stella follows, this must be true.

 My question is: Stella sees Terrence in her ultra-powerful telescope
moving away from her with an apparent speed of 0.4444c, and for 9 years.
Is it true, or is it not true?
On the way back, for 9 years, she sees Terrence coming back to her for 9
years, with a speed of 4c.
Is it true or is it not true?
If it is true why not say it?
In his human trickery, man is very intelligent, he intuitively KNOWS
that
he cannot say it.
If he says: it is false. He makes a fool of himself.
If he says: it is true, he knows that we will answer, and what distance
does the earth travel in both cases?
And this is frankly intolerable for relativistic believers who see their
God naked, and his two laughable German prophets.

For this, you will have to check the math in my table.
There is no such thing as a 4c approach.
You've made some stupid math errors.
Really, really STOOPID math errors.
