I think the methodology and the logic behind it is not clear to some. So let me explain a bit. Lets consider the below example.
| Inn | No | Runs | Avg | SR |
A | 100 | 0 | 5000 | 50 | 60 |
B | 100 | 20 | 4000 | 50 | 60 |
There is not one metric in which B is better than A. One might argue that B has been dismissed 20 times lesser but that is because he has faced less number of deliveries. Their balls faced per dismissal is the same. Whereas A has scored more runs than B hence deserving of more points. Whether A is really better than B is another matter but clearly he is deserving of more points because he has scored more runs.
Another way of wording 'batting avg. adjusted for not outs' would be 'runs per innings adjusted for not outs'. A batsman with an avg. of 50 means each time he ended up not out he would have scored 50 more runs. I am knocking off 25% of it because he did not actually score those runs.
I know that batting avg and not outs can be an endless debate. But I will get back to the countdown now.
