It's been said before but 50 overs in 3 hours, just below 17 an hour, we've done it a few times and the umpires praised us for it saying, we don't see that very often. however what i've actually seen, majority of the umpires take alot of time walking to their ends or even finish what they are writing down... given that this may last 30 seconds some times, that's an extra 25 minutes per innings, and nearly an hour for both! Which can make alot of difference!
We were forced not to bowl our seamers last year in a bid to finish the match off, it was getting dark but the batsman could see fairly well as they were tonking the medium pacers about pretty well. It got darker and darker, and the umpires told our captain he has to bowl 2 spinners, he turned around and said i dont have 2 spinners, let's not argue about this the less time we spend discussing it the quicker we will be done. Needless to say it ended in a draw due to umpires taking their time to begin with, had those 25 minutes for innings been nullified, we would have been able to bowl our seamers and finish them off.
