Just a random thought - maybe I should switch the RGB flash order to have the least-ghosting colors first. Since the ghost-correction algorithm is never going to be perfect, you'll always be able to detect at least some subtle ghosting. In looking at the tests I've done so far, ghosts of the future seem much more disturbing than ghosts of the past. Either your used to perceiving after-images from moving objects, or the notion of them doesn't seem odd. Pre-images of what is about to happen is outside our normal experience, and looks really distracting in the GIF loops. If I put the flashes in R (least ghosting), B (medium ghosting), and G (most ghosting), the ghosts are mostly from past frames, which should look less distracting. I think.
