I think you need as an umpire to use your own judgment and eyes instead of always being at the whim of the technology cause that can sometimes fail. except for ball tracking cause that’s a completely different context and your judgement can’t predict the future to as much accuracy but snicko has been proven to sometimes not show obvious nicks before. You could see with the naked eye that the ball had clearly hit something and had changed trajectory, it’s basic physics to imply that it has hit something and the only thing it could have hit was glove or bat
