It's not that simple, and perhaps that's the huge problem.
Knowing the mass of a particle is simple.
Knowing the energy, or momentum of the particle, is simple.
So knowing your speed (observable, real or apparent) Vo, Vr, Vapp, is very 
simple.
But how do we know our own acceleration?
Isn't acceleration measured in the lab reference frame?
In this case, it is the acceleration measured in the lab, and it is not 
the real acceleration.
If we do not know a, then we cannot verify what is theoretically obvious 
which logically dictates that Voi/c=[1+c²/2ax]^-(1/2)


> There is a known relationship between the two.

 Yes, but is a local acceleration... it always change in the time and in 
the space.
