Then a total of only one hour is wasted if every DRS is wrong.
This is a massive problem in modern cricket. There is so much time wasted, it's absolutely ridiculous and you now want to waste another hour on the DRS? The worldwide average over rate is barely at 12 overs an hour and it should be at, at least 15!
Before physics and drinks breaks and all this were introduced teams would average basically 20 overs an hour. Granted we are talking the best part of 15/20 years ago but it shows it can and did happen. If you then want to waste another hour of playing time we may as well just not play cricket.
There isn't a massive need for snicko in the game as there is slow mo replays and Hotspot. Also, the key idea of the DRS which people seem to overlook constantly is that it is meant to overturn massive howlers, not incredibly tiny details or ridiculously close calls. The BCCI are claiming they won't use it because it's not 100% accurate, well then why are they going by the umpire decisions? If they want foolproof umpiring which is only 100% right all the time then they shouldn't be playing cricket.
In my opinion, they seem to be going against it mostly for the sake of it. All of their main reasons are flawed and they can't even complain about financial issues.
