Bowling · Loading & Bound

What is the bound in a bowling action?

The bound is the jump from back foot to front foot that sets up the delivery stride. amp reads its height and length, and classifies the action type — side-on, front-on or midway — because what counts as correct downstream depends on which action you actually have. Two criteria, 8 points of 100.

These are the criteria as amp scores them. Reading your own footage against them is free and always will be — what amp adds is doing it the same way every week, so the change between one session and the next is a number rather than an impression. Apply for the pilot.
