If the runs scored in an over are equal to the current run-rate and the numerical value of the current over, the run-rate is increased by 1.
For example, if the Delhi Daredevils are pwning the Kings XI Punjab, and score 152 in 15 overs, their current run-rate is…
So now, Piyush Chawla is sent into the attack. At this moment, Virender Sehawg is batting at 78. He’s really angry, that Chawla was picked ahead of his Delhi buddy Amit Mishra in the World Twenty20 squad. So he goes all boom, bang and all that.
Do note, that Chawla is bowling the sixteenth over. So Sehwag scores ten plus sixteen runs in the over, which equals to twenty-six runs in the over. That takes the total to 178 of 16 overs.
