According to Jeremy Lloyds, who officiated in the triangular Limited Overs series between India, Pakistan and Australia in Holland this week, keeping his eyes fixed on the batsman till the bowler delivered the ball was a tougher task.
"It may actually be easier for the umpire to look down at the popping crease as the bowler ran up and then shift his attention to the ball's flight," Lloyds was quoted as saying in Daily Telegraph in London.
The ICC recently decided to use technology on a trial basis to call no balls whereby the third umpire will spot the same on video and convey it to the on field umpire through wireless.
The system will be experimented in the Champions Trophy in England next month where 12 teams would be competing.
The idea behind the experiment is to allow the on-field umpire at the bowler's end to focus all his attention on the batsman - to concentrate on what happens to the ball after it leaves the bowler's hand without any distraction from his most important task.
Unfortunately, in Holland, only the final could be played for 50 overs each side after rains washed out two league matches and another was reduced to 33 overs a side, rendering any feedback from the umpires superficial.
