The more this World Cup goes on, the more it seems the Umpire Decision Review System (UDRS) could have a very important part to play in deciding the eventual champions.
So far, the usage of the two appeals per innings system has been intriguing.
Of all the people who you would think would use it most dispassionately and judiciously, the learned Kumar Sangakkara would be top of my list.
The Sri Lankan captain is a student of law who prides himself on gathering all the evidence then responding unemotionally.
Yet his use of the UDRS in the Pakistan innings on Saturday was so dire it was comical.
Rangana Herath, his bowler, did not really even appeal for the lbw which Sangakkara seemed so certain of from his viewpoint behind the stumps.
On review, Umar Akmal, the batsman, had smashed the ball so hard it had come nowhere near his pads.
The Sri Lanka keeper may briefly have had egg on his face, but it was short lived. The lasting damage is only felt by the umpires.
Daryl Harper, the elite panel umpire from Australia, hates it, and you can understand why.
After confessing to having a crisis of confidence since the system was introduced, it has followed him around more than anyone.
In the Sri Lanka-Pakistan game, all the reviews came at his end, rather than that of the outstanding Ian Gould. It was cringeworthy.
At one point, both big screens were trained on him, while everyone awaited the decision for so long that he had to mime a "hello" and wave to the camera just to break the spell.
