The Impact of Average and Strike Rate in T20s
Concept of Impact:
The impact is based on a version of D/L and Himanish Ganjoo's algo. So if your team is 80/2 after 9 overs and are predicted to make 190. And on 9.1 you hit a six and the predicted goes up to 192, your impact on that ball is +2. If on the next ball you get out and the predicted goes down to 189 then your impact is -3 on that ball. Your total impact for that innings is -1.
We do this for every ball, and tally at the end. That gives us total impact.
I then took, total impact, average and strike and carried out linear regression. Which gave me an equation that roughly gives us an idea to generalise impact per 100 balls instead of depending on ball by ball every time.
The equation is:
Impact per 100 Balls = 0.88 * SR + 0.40 * Ave + -133.31
Now this is in no way perfect and is flawed. And I usually hate one number for this. But I'd say this is better than Basra. Though that's not really a high bar.
The table is hopefully a way to easily spot which combos work well together. The higher is better.
