We said we were here to change the game. Here it is. The Balance Point Index (BPI) is an inferential metric that for the first time ever, allows you to measure the pick up and swing of cricket bat A BPI figure is produced by an algorithm that incorporates the various mass and physical properties on a cricket bat (such as weight, balance point and shape) to provide a number on a scale of 1 – 100. There is no such thing as a good or bad BPI figure – instead there is a perfect BPI for each individual.
