Think about the things mentioned and how much focus some put on them and how little they truly matter with bowling balls and THS conditions.

People refer to the dual angle method like it does something different then just eyeballing a drilling. The D.A.M. and 4x4x4 and anything else are all different ways of saying the same thing. The D.A.M. method is a precise way that says the these drill angles give you this kind of reaction, this pin to pap difference effect it this way, then the VAL angle gives you these characteristics. You can do the same thing by eyeballing it, the ball doesn't know the difference. Duplicating it, the DAM would be the exact way, where as the eyeball method gets you in the ball park.

Now I have played with the BP software and tried using different pin to pap distances on the same layout, different MB positions, different side weights ect and it shows on a THS that the differences are minimal. Surface was always the bigger factor.

First pic is a ball with 1oz positive side weight, no side weight, then 1oz negative side weight graphed in that order.



Second pic is a outburst drilled 30 X  3" 4" 5" 6" X 75 in that order

Yeap, that's pretty much what the ball motion study said.  And one of my points about the dual angle (as said in one of my articles) was the same as what you said, it's not some radical wild way to lay stuff out, it's just adding a bit of precision or maybe more accurate repeatability . .

Or to sell Pro Sects

Thanks for posting that.  Two question:

1. For pic #1 you have pin up vs pin down.  Why keep the angles the same and move the pin to pap distance?  When I think pin up vs pin down, I think the same pin to pap distance, but changing the drill and val angles.

2.  What shot did you use .. if it is a house shot, is that what is reducing some of the effects of the drilling changes, or will you sill these small differences on any shot?

Pic #1

Here is a Taboo with two different layouts (pin up vs pin down)

30x3x50 vs 30x6x50 chart

pic #2

Same  Taboo with two different layouts (mb by val vs mb by thumb)

30x5x40 vs 30x5x80

Used the wrong pic. That was a 3" pin vs a 6" pin on the same layout. They get to be very similar if you don't pay attention lol.

Made the correct update to the pictures and the angles.

The shot used was a house shot pattern. Didn't really try many of the others during the free trial like I had wished. THS blend the looks of a lot of different layouts and bowling balls.

 For those who were curious about a video, I remembered this from a while back.
