That's giving some credit or tolerance to on field umpires
.. Keeping human factor alive..
Earlier they had 2 out of 3 conditions is enough to overturn On field LBW decisions. .
Now all three required ! Giving advantage to batsman.
With Technology available, u can play the game perfectly without on field umpires also...
It's the traditional human factor , still we want to keep...
Using Technology to eliminate the obvious blunders..not to overturn every decisions...
India can opt for on field umpires decision for run outs also in their argument. ..How u expect an umpire to estimate the projectile with naked eyes & could not decide the run out decision which can be done with naked eyes !!!
