Formula:
NRR=(total runs scored/total overs faced )-(total runs conceded/total overs bowled)

Scenario's:



1. Side that bats first wins

  • Team A bat first and set a target of 287-6 off their full quota of fifty overs. Team B fail in their run chase, early losses causing them to struggle to 243-8 in their 50 overs.
  • Team A's runrate is \frac{287}{50} = 5.74
  • Team B's runrate is \frac{243}{50} = 4.86
  • Team A's NRR for this game is 5.74 − 4.86 = 0.88 Assuming this was the first game of the season, their NRR for the league table would be +0.88.
  • Team B's NRR for this game is 4.86 − 5.74 = −0.88. If this was the first game of the season, their NRR for the league table would be −0.88.

2. Side that bats second wins

  • Team A bat first and set a target of 265-8 off their full quota of fifty overs. Team B successfully chase, getting their winning runs with a four with sixteen balls (2.4 of the 50 overs) remaining, leaving them on 267-5.
  • Team A's runrate is \frac{265}{50} = 5.30
  • Team B faced 47.2 overs, so their runrate is \frac{267}{47.33}  \approx 5.64
  • Assuming that Team A and Team B had previously played as in the game in scenario one, the new net run rate for team A would be \frac{287+265}{50+ 50}-\frac{243+267}{50+47.33} = \frac{552}{100}-\frac{510}{97.33} \approx 0.28

3. Side that bats first is bowled out. Side batting second wins.

  • Team A bat first and are skittled out for 127 off 25.4 overs. Team B reach the target for the loss of four wickets off 25.5 overs, scoring a single to win the game and end with 128 runs.
  • Despite Team A's runrate for the balls they faced being 127 / 25.667 = 4.95 (2dp) because they were bowled out the entire 50 overs are added to their total overs faced tally for the tournament, and Team B are credited with having bowled 50 overs.
  • Team B actually scored at a slower pace, however they managed to protect their wickets. Thus, only the 25 .(5/6) overs are added to the seasonal tally.

4. Side that bats second is bowled out. Side batting first wins.

  • Team A bat first and set a formidable 295-7 off their complement of 50 overs. Team B never get close, being bowled out for 184 off 35.4 overs.
  • As in scenario 2, 295 runs and 50 overs are added to Team A's tally.
  • However, Team B, despite facing only 35.4 overs, have faced 50 overs according to the NRR calculations, and Team A have bowled 50 overs.

5. Both sides are bowled out, the team batting first therefore taking the points.

  • Team A bat first, and manage 117 off 24 overs on a difficult playing surface. Team B fall agonizingly short, reaching 112 off 23.3 overs.
  • In this case, both teams get 50 overs both faced and bowled in the overs column for the season, just as in example 1.
