Nah, not garbage, just BETA.
Unless you are paid to play it's just not possible to hit 10 shots with a 6I from the same place all within a few feet of each other consistently. I've played for 19 years, I have a single digit handicap and I still can't do that. Too many little things can go wrong. An open clubface, blocked hips or turning the wrists too early all will cause a mishit and none of those things can be accurately recreated with this simple timing bar. Those missing elements need to be represented somehow or otherwise "beginners" like yourself walk onto the course and shoot par. IMO, that's not very realistic at all. It took me 7 years from the time I first picked up a golf club to shoot par (72) in real life. I'm not saying it needs to be 7 years here as well but, there does need to be some sort of a learning curve.
