To make it even more easier, we can use all the available standard data, the Team Average Score and Opponent Average Score.
At Present:
Team Average Score: 166
Opponent Average Score: 211
Statistical Gap: -45
Before The Asia Cup:
Team Average Score: 165
Opponent Average Score: 212
Statistical Gap: -47
Before Whatmore (May 2003):
Team Average Score: 164
Opponent Average Score: 215
Statistical Gap: -51
So, we made improvement of "2" Statistical Gap during the Asia Cup and "6" Statistical Gap by Whatmore. This proves Whatmore actually made improvements!
