I am curious in answers to the following questions.

Assuming the same bowler is doing the throwing of the ball....

How much of a percentage of the reaction of a bowling ball comes from a certain aspect of the ball design?

 1. The cover stock (or surface) is responsible for __________ % of the reaction.
 2. The weight of the ball is responsible for ________% of the reaction.
 3. The core design is responsible for ________% of the reaction.
 4. The drill pattern is responsible for _______% of the reaction.

I am curious as to what kind of numbers people would ascribe to each of the
blanks above.
