ball strike line paths question

[Etrain]

on company websites they have a graph showing the strike line of the bowling balls. My question.... is there a science to doing this? Do they all use the same technique therefore have accurate strke lines? Or do they just choose random bowlers with different rev rates to make the strike line??

thanks

Pretty much a little bit of all of those, from science and computer modeling to real bowler's testing new ball designs.

thing to remember is, those are just basic guides to how the ball will react. With different lane conditions, layouts, bowler styles, the ball path can be very different.

ok thanks ... i usually look at this when i go ball shopping and compare the lines to my existing ball, But being when i look at different companies im not sure if there lines are as accurate as my balls company.

I wouldn't recommend judging what you buy off of those charts. You're better off watching reaction videos with bowlers who throw the ball similar to you to see how the ball reacts.
