The problem is that the A-vector field has no direct measurements with 
current technology.  It CAN be computed, but there is no empirical 
feedback on whether the computations are correct.
The nearest [failure] analogy is various kinds of subatomic particle test 
analyses.  It is necessary to reconstruct the particles from very minimal 
data.  However, the reconstruction is subject to a number of empirical 
constraints: we need conservation of mass-energy, conservation of 
momentum, the CPT symmetry [all of these are similar]: and the fool 
tracks must go where they were observed!  We currently lack the 
technology to measure the A-vector field.  We do have the technology to 
measure the electromagnetic field.
In essence, the above experiments were designed to effectively shield the 
electrons from the electromagnetic field, reducing the experiment to the 
control case in this respect [this can be measured] while maintaining a 
distinct A-vector field from the control [this CANNOT be measured, only 
computed!]  It was found that the electrons were still 
accelerated, in spite of no measurable differences in the electromagnetic 
field; and furthermore, these accelerations were within measurement 
tolerance of those predicted under the A-vector field model.
