Was floating an idea with a group chat for ER, that increased incrementally with each over bowled:
Under 4 an over -
1 over: 5 points
2 overs: 10 points
3 overs: 15 points
4 overs: 25 points (bonus 5 due to bowling full quota.
4.01-5 -
1 over: 4 points
2 overs: 8 points
3 overs: 12 points
4 overs: 16 points (bonus 4)
You get the idea.
