India and DRS

Did you see how well DRS worked just now?

It's a good system, just needs better understanding by the third ump.

When I read statements that DRS gets 90% or 95% calls right, I wonder what the basis is.

People who says that are giving 'positive predictive value'.

What is it validated against? Human eye? Botham's? Husain's? Or, that idiot pundit who sits at his home in pyjamas in front of telly and writes commentary for Cricinfo?

All of the above.

What is the basis to state that DRS has 95% positive predictive value? To what standard was it standardized?

Afridi - stats you have just mentioned.

The floor is yours sir.....

Pisss it off now, get back to umpires making the decision................it's making the game a joke.

Neon, no offence but next time you create an article at least have the decency to back up your sources. All you said was bbc- you got any quotes from Stewart and Vaughan saying we should abolish DRS??

As for your query- I'll take the floor


The referral may well system end in a few incorrect decisions, but according to ICC statistics the DRS leads to a correct decision rate of 97 percent, noticeably higher than the rate of 90 percent without it- here's proof!!

Ps, if you looked at the furst ashes test the umpires made a total of 72 decisions, which is "well above the average (49) for a DRS Test match".
The umpires were assessed too have made 7 mistakes, of which 4 were corrected by DRS, meaning the officicals got 90.3 percent of decisionss correct and this climbed to 96.8 percent as a result of the use of the review system!!!! There you go!!

It was a very quick Google search

Disagree about Dr's getting everything right. Hawkeye - how do we know his accurate it is in predicting where the ball will end up? I'm questioning the technology itself.
Backing it with stats validated by the technology itself proves nothing.

Like I said.. It just takes too much away from the game itself. I'd rather umpires just make the call

If India is given the choice between DRS and Bucknor, which would you prefer?
