Any England win, the group is decided on points and NRR becomes irrelevant:
| Team | Points | NRR |
|---|---|---|
| England | 8 | ? |
| South Africa | 6 | ? |
| West Indies | 4 | ? |
For completeness, if the match is rained off, the group is also decided on points:
| Team | Points | NRR |
|---|---|---|
| England | 7 | ? |
| South Africa | 6 | ? |
| West Indies | 5 | ? |
If West Indies win, things get more interesting – all 3 teams will be level on 6 points, and NRR comes into play. Let’s assume England bat first and score 130.
West Indies chase 130 in 20 overs:
| Team | Points | NRR |
|---|---|---|
| South Africa | 6 | 1.382 |
| England | 6 | 1.247 |
| West Indies | 6 | 1.244 |
West Indies chase 130 in 15 overs:
| Team | Points | NRR |
|---|---|---|
| West Indies | 6 | 1.836 |
| South Africa | 6 | 1.382 |
| England | 6 | 0.863 |
So if England score 130 and lose very narrowly, they can go through; but if they lose anything other than narrowly, they will fall behind South Africa on NRR and go out. This goes for scores up to 134 – if England score 135+ and West Indies win even narrowly, England will fall behind West Indies and South Africa on NRR.
What if they score 199?
West Indies chase 199 in 20 overs:
| Team | Points | NRR |
|---|---|---|
| West Indies | 6 | 1.428 |
| South Africa | 6 | 1.382 |
| England | 6 | 1.380 |
West Indies chase 199 in 15 overs:
| Team | Points | NRR |
|---|---|---|
| West Indies | 6 | 2.109 |
| South Africa | 6 | 1.382 |
| England | 6 | 0.938 |
So England still go out if they lose!
Finally… let’s try 201!
West Indies chase 201 in 20 overs:
| Team | Points | NRR |
|---|---|---|
| West Indies | 6 | 1.433 |
| England | 6 | 1.384 |
| South Africa | 6 | 1.382 |
West Indies chase 201 in 15 overs:
| Team | Points | NRR |
|---|---|---|
| West Indies | 6 | 2.117 |
| South Africa | 6 | 1.382 |
| England | 6 | 0.940 |
So… South Africa are through unless England very narrowly lose a very high-scoring game; and England will out out if they lose, unless they lose very narrowly and score either 134 or less or 201+.
(Or am I wrong?!?!)
I concur with your figures.
Suffice to say South Africa should be feeling a lot more confident of qualification than either England or the West Indies.
