So if my putt is 18 ft, not uphll or downhill, and i am using the bar that is marked '30 ft' and i move my pointer to just under half of that bar, my math says it would be around 15 or so that i'd hit it. So when i hit it past the hole... how does that work? What a joke of a game. I've tried it a few different times and it blows my mind how inconsistent it is.
