easy victory for our boys in the end and once again i have to say you have gone wrong with the NRR . You have calculated the NRR for every single game and just added the efeective NRR . EG : In first game for SL, nrr was +1.34 and in 2nd game its +1.40. So you have added both and got +2.74. Its not like that ,
Just add the total runs in both games and divide it by total overs batted . Repeat that by calculating total runs conceded in both games and divide it by total overs bowled . Now find the difference between first and second .that will be your NRR
