Not without losing precision... I'm no wordsmith; what I said above is exactly what I mean, within the limits of my understanding of language.
There are definite values of spacetime that separate objects. How those values are communicated may vary based upon the one doing the measuring - units, etc - but that spacetime remains the same, regardless of who is measuring it.
The measurement of said spacetime may vary due to the movement of the person making the measurements in relation to the movement of the objects involved - this is where relative observer bias starts to come in. However, that movement also has a definite value that relates observer to observed.
For example, if I set up a scenario whereby I am measuring the distance between two stars as I pass by them at 25,000 Kph relative to my own planet of origin - and that planet, in relation to the two stars, is moving through space away from them at 12,000 Kph - this establishes a frame of reference for the entire problem, in which my motion, the motion of the two stars being measured, etc. all go into a single calculation that will give me a definite value of the spacetime between the two stars. It also gives enough knowledge to be able to cancel out observer relativity and come up with a single, definite value for those measurements.
(Over-simplified, but the core concepts are there)
In other words, relativity admits to measurements being different with relation to frames of reference, but also includes the means to calculate to take those frames into account - thereby resulting in definitive values.
Sorry, Bodhi - some things can't be rephrased easily by one who thinks in symbols.
