Have we measured the change in the red shift over time?

[QUOTE="Justin Hunt, post: 5998228, member: 637066"] Have experiments been done to measure the red shifts of distant objects over time? If inflation is correct, the the speed at which an object is receding relative to us is based on how far away that object is located. Therefore, the most distant objects would also have the highest acceleration. Is it possible to measure a change in red shift of distant objects due to this acceleration? I am a bit of a skeptic of the expanding universe conclusion we derived by comparing red shift values to brightness when it could be explained with actual velocities versus expansion of space time or some combination of the two. In my opinion testing changes in red shift over time would be the most decisive way to determine what part of the velocity is due to actual velocity and what part is due to the expansion of space between us and the distant object.
