Creating a Layout
What happens when you create a layout
When you create a layout, whether using Dual Angles or the Pin Buffer System, what are you actually doing? Tilting the core on a angle in relation to the bowler's axis? Yes, that is correct, but what are you actually doing? Changing the amount of flare? Absolutely, but what are you actually doing?
Think about it, what you are really doing is changing the rate at which the axis migrates. Axis migration begins as soon as you let go of the ball and it will follow an RG curve. When the ball responds to friction the axis migration speed will increase. The faster the axis migration the more shape the layout produces, the slower the axis migration the less shape the layout produces.
What a layout looks like is not important, how a layout influences motion means everything.
Angular, Faster, Forward
Angular, Normal, Hook/Set
Smooth, Normal, Continuous
Smooth, Normal, Low Flare
Reaction Shape
In the Paddock App these shapes are determined from the ratio of the Drilling Angle (DA) to the Vertical Axis Line Angle (VALA). These reaction shapes, from most to least, are
Angular (DA:VALA is 3:1 or greater) ie layout 80 x 4 x 20
Strong Arc (DA:VALA is 1.5 to 3:1) ie layout 60 x 4 x 40
Arc (DA:VALA is 1 to 1.5:1.5 to 1) ie layout 45 x 4 x 45
Smooth Arc (DA:VALA is 1:1.5 to 3) ie layout 40 x 4 x 60
Smooth (DA:VALA is 1:3 or greater) ie layout 20 x 4 x 80
Transition
The sum total of the angles will determine how soon the reaction shape will start after the ball responds to friction. This is known as Transition in the Paddock App. When wanting more reaction shape the sum total of the angles should be less because you want the shape to start as soon as possible when the ball responds to friction, and when wanting less reaction shape the sum totals should be more because you want the shape to start after the ball responds to friction. RPM of the ball will also be a factor. Bowlers with lower RPM will tend to benefit from faster transitions, lower sum totals, and bowlers with higher RPM will tend to benefit from slower transition, higher sum totals. When creating a Dual Angle Layout in the Paddock App it is recommended to set the transition slider to a setting that compliments the reaction shape desired.
Ball Roll Motion (Flare)
The Pin to PAP (Positive Axis Point) distance determines the amount of flare potential as a result of the Dual Angle Layout which is Ball Roll Motion in the Paddock App. The percentages are,
Continuous 80% to 100% potential
Forward 60% to 80%
Hook/Set 40% to 60%
Low Flare 40% or less
The overall core construction of the bowling ball will determine the flare potential, the Pin to PAP distance will determine how much of that flare potential you will generate. ie., if a ball has an undrilled flare potential of 6", according to the manufacturer, the amount of flare that you could expect will be,
Continuous 4.8" to 6"
Forward 3.6" to 4.8"
Hook/Set 2.4" to 3.6"
Low Flare Less than 2.4"
Bowler Metrics
The bowler's metrics Axis Tilt, Axis of Rotation, RPM, and Launch Speed.
The bowler's Axis Tilt, Axis of Rotation, RPM, and Launch Speed will have an effect on the bowling ball's overall motion. The bowler's metrics can change the amount of shape, transtition time, and flare potential. A higher axis tilt, higher axis rotation, higher RPM, and slower launch speed bowler will have a greater overall ball motion and greater reaction shape then a lower axis tilt, lower axis rotation, lower RPM, and higher launch speed.
The Paddock App will calculate the Dual Angle Layout based on the bowler's metrics entered into the app. The Dual Angle Layout created is the optimal layout to produce the reaction shape and motion that the bowler desires.
