The Hawk-Eye technology predicts the path of a ball. Bounce and deviation off the surface are two key aspects under its scrutiny.
The bounce depends on several factors including the height from which the ball is delivered, the pace and length of the ball, the hardness of the pitch and the amount of grass on it, which part of the ball hits the pitch, how old the ball is and the amount of moisture in the pitch.
Question: Does the DRS have enough data on all these factors to predict accurately how much the ball will bounce?
This includes how much the ball will move or spin after pitching.
When spinning: The amount of spin depends on the number of rotations on the ball. There can be a spot on the pitch that offers different kind of grip and makes the ball spin more or less (like the bowlers' footmarks).
Question: Can the DRS device predict accurately which spot of the pitch offers how much turn? Also, how does it predict how much the ball will turn when it hits the pad just after hitting the pitch without having travelled enough to give anyone an idea of how it'll behave?
