Man I can't blelieve you screwed this up this bad you have generally seemed to at least be able do basic math. 1 - Where k = comparative tick rate. v = k* (d / t). You can see that d can never change if you retain the known and calculated physical affect of time dilation on the clock making the trip. 2 - What biased velocity? You are dreaming. 3 - Why would anybody want to attempt to do that is is not required and has not been claimed. 4 - Ditto.
