Better to bat/bowl first in big games?

[mancalledsting]

World Cup Finals:

 

Bat first win percentage: 7/11 (64%)

Bowl first win percentage: 4/11 (36%)

 

World Cup Semi Finals: 

 

Bat first win percentage: 12/22 (55%)

Bowl first win percentage: 10/22 (45%)

 

Champions Trophy Final:

 

Bat first win percentage: 2/7 (29%)

Bowl first win percentage: 5/7 (71%)

My conclusion, with increasingly higher stakes (i.e. WC final > WC semi final > CT trophy final), batting first gives a slight advantage.

Definitely bat first
