Brad Haddin's faint nick behind with Australia 15 runs short of a miraculous first Test Ashes win at Trent Bridge proved a correct call by DRS.
But for Haddin to be given out for a feathered touch on the ball further highlighted how ridiculous it was that in the same match, England's Stuart Broad managed to survive at the crease despite giving a full-blooded edge to slips.
DRS is getting the line-ball calls, but missing the shockers - even though the whole purpose of its introduction was to eliminate the blatant errors that frustrate fans and change the course of matches.
In such a tight Test, the 28 runs Broad scored - after he should have been out in the second innings - ultimately proved telling.
Australia lost out on four umpiring calls throughout the match on lbw referrals.
And a major factor in the match was that England clearly used their reviews better than Australia.
Clarke had no reviews left when the Broad incident happened.
Yet even in gripping climax to the match, England skipper Alastair Cook had a review up his sleeve to overturn the original not out call on Haddin.
Clarke refused to blame the umpiring, and admitted he needed to improve at using DRS.
"That's the way the system is unfortunately. If I'd used my reviews better, I would have had an opportunity to use it when there's a howler like that," Clarke said.
"We've still got two umpires on the field they're still the most important people out on the ground, those two umpires. They make their decisions and, as a player, I've been brought up to live with the decision of those guys.
"The DRS has been introduced for the howler - there's no doubt about that. I don't know the answer to your question (how to fix it). What we've got is the same for both teams. That's all I can ask for."
Cook also had no answer on how to eliminate the howler.
But he said using DRS should be a tactical thing for captains.
"I think the bottom line with the review system is it does get more decisions right. Well it should get more decisions right is probably the best way of saying it," he said."Because it's such a big game, it's so important that decisions are right because they impact the game. I think both sides feel that."
