Ten Pin help needed -- Sorry if covered before.

[J Anderson]

You know what Mike, we're not going to agree. You showed your side and Me mine. It's up to everyone else to decide who they want to go with.

I don't think I'm going with either one of you. The pocket is not a single point. Even if it were the average person can not see a half inch difference at 60', let alone hit it consistently.

Looking at the graph that Bowl1820 posted I would say the pocket is that area where the strike percentage is greater than or equal to 95.

And I agree with you J. You don't have to hit that exact spot and nobody is going to hit it consistently.

All I said is that the pocket is generally considered at approx. the 17.5 board. Which is the half way point between the center points of the 17 & 18 boards.

And that the studies showed a 2.5" offset offered the highest percentages of strikes and that point falls at that spot on the boards.





And I apologize to the O.P. For us hijacking this thread.

Wow this thread got very mathematical..making my head spin!

Back in early August I was at a trade show, talking to one of the ball reps from either Storm, or Motiv. If it was Storm it would have been Boomershine.

The topic of that angle of entry test came up. The testing method was described as a ramp delivery system to control the angle, "offset", and speed of the ball.

The "offset" is related to the probability of getting the 7 pin out.

The deflection is related to the probability of getting the 10 pin out.

Since a ball on a ramp has no axis tilt, it effectively has rolled out.

When a ball has rolled out, it has to hit higher (less offset), to carry the 10 pin, but too high and you leave a 7 or 4 pin.

The graph only focused on the strike and ten pin.

Wow this topic just happened to come up at trade show back in August, funny you acted like you never heard any of this before back at the beginning of this conversation. I know you forgot and just remembered.

Now they may have used a ramp back when they first came up with this.

But in the usbc pin carry study they tested speed and rev dominate type bowlers and balanced types and used 3 different ball types.

I think they had some tilt on the ball and it wasn't rolled out. And it still showed 2.5 had the highest strike percentage.

Be that as it may.

You said the the optimal location is 3.33" well prove it.

Post your test data, the videos of the tests etc. not just some lane specs with a couple of numbers added or subtracted.

The 2.5" offset at least has been tested and has some data backing it up and grant you even the Usbc says they need updated data at least they have some.

As I said before

We stated our cases, let everyone make up their own minds.

Of course we both know your right and I'm wrong and anyone agreeing with me is wrong also.

Update: I just found some new info Mike is right, he doesn't even have to prove it now. And the thread can go back to being about ten pins, (everyone shouts Hooray!)
