Melbourne, July 18: Their may be a conscious drive to reduce the number of errors in decision-making on the 22 yards and that is why technology has been employed. But former Australian umpire Daryl Harper feels the gamut of gizmos used collectively doesn't constitute "the aid it is claimed to be."
The retired official who put in his papers prematurely after some blunders by him spawned much criticism from various quarters, including by India captain M S Dhoni, expounded on the opinion that technology can not be depended on.
"When a batsman plays a shot well away from his body, and you as an umpire see the ball strike a glove, go through to the keeper, and you hear the sound, you can draw no other conclusion than it has been gloved to the keeper and the batsman is out," Harper said.
Harper pointed out a blatant discrepancy with the technology being used.
"That it can't be confirmed by a camera at 25 frames per second, that's technology's problem. If they were filming at 1800 frames per second, like those super slow-mos, you'd see the glove depressed with the contact from the ball," he added.
Harper went on to say that the technology has not arrived at a sufficiency required to reach a conclusively correct decision.
"At 50 frames per second there is a very slim chance of the ball ever being captured making contact with the pitch when it actually lands, because there is a minimum of 60cm (of the ball travelling) between frames," Harper said.
"If the cameras cannot capture the ball touching the pitch, I'm not quite sure how they can claim the degree of accuracy they do claim."
Harper concluded that a reliable technology is still in its nascent stage and needs a lot of trial-and-error before being reintroduced in international cricket.
