I found an interesting paper on using a computer to test latency of professional skeet shooters. http://www.sciencedirect.com/science/article/pii/S0042698903002992 http://www.sciencedirect.com/science/article/pii/S0042698903... The most interesting thing I learned about was the three modes of Saccadic latency. I wonder if there are aspects of computer GUIs that work for or against the three modes. Or decades later in 2017 if the three mode idea is still current thinking in the field. The variation of Saccadic modes does exceed your prediction of 40 ms. I would assume it would be easier to test latency of FPS video game players rather than simulating skeet shooting using a FPS-like computer system. In fact that would be a novel scoring, ranking, or handicapping system for a FPS.
