This is true but it's actually even more "interesting". The predictive part is reasonable good, but more fundamentally it can't tell EXACTLY where it hit the pad. By it's very nature a leg pad is soft and designed with some give. This complicates the calculation. For example a ball turning 4 degrees from straight and hitting a pad 2m from the wicket. The difference between the pad giving 5mm and giving nothing when the calculation starts - would translate into 1mm by the time you get to the stumps. Also for anyone that has ever played cricket and stuck a set a wickets into the ground - the width is supposed to be 9 inches across. But that is not measured exactly each time a stump is removed. So they could be 1 or 2 mm out easily.Not sure about the particular incident but umpires call allows for a margin of error in the tech. When the tech shows an incredibly close call, flicking a bail for example rather than whacking it, they stay with the umpires original decision. The tech is good, it isn't perfect as it is assuming what is going to happen. It doesn't actually know as fact.
I like that aspect and players have faith in the umpires. Their success percentage is phenomenal, no one who stands at this level is even average.
