Instant Replay
Computer-assisted video tracking technology has improved to the point that it can determine the position of a ball at impact with a margin of error less than five millimeters. Accordingly, starting with the NASDAQ-100 Open in March 2006, most top-level tournaments allow systems such as Hawk-Eye to be used to settle disputed line calls.
Players are allowed to appeal to Hawk-Eye on disputed calls with a limitation: They lose the privilege if the appeal goes against them three times per set, with one more challenge allowed during a tie-breaker.
In the 2006 NASDAQ-100 Open, challenges by men were upheld 38% compared to 27% for women (skewed by Maria Sharapova, who went 0 for 11).
At the Championships, Wimbledon 2008, in the mens singles challenges were successful 29% of the time with an average of 6.6 challenges per match, in the women singles challenges were successful 20% of the time with an average of 3.8 challenges per match.

Famous quotes containing the words instant and/or replay:
“The true picture of the past flits by. The past can be seized only as an image which flashes up at the instant when it can be recognized and is never seen again.”
—Walter Benjamin (1892–1940)
“One reason writers write is out of revenge. Life hurts; certain ideas and experiences hurt; one wants to clarify, to set out illuminations, to replay the old bad scenes and get the Treppenworte said—the words one didn’t have the strength or ripeness to say when those words were necessary for one’s dignity or survival.”
—Cynthia Ozick (b. 1928)
