Not criticiseing matey just asking what tests have been done. THe thing being its not reaction as such that makes the blocking or slipping of a punch effective, its the movement or action before the shot byou react to. Its the permatation of lots of things. The eye sense or message doesnt go direct to the brain its the only sense that doesnt. I would think it could give bad habits, like waiting for the action rather than avoidance. Just curious , wish you well with it.
