Spin efficiency is multiplied by raw spin
- When a pitched ball’s spin efficiency is multiplied by raw spin, we are given the True Spin of the ball.

Feb 1, 2018 · True Spin (or Useful Spin) only reflects the components of spin that contribute to movement. For example, a fastball may have a total spin rate of 2,200 rpm. However, after a little bit of analysis, we may realize that 500 rpm of that total spin is perpendicular to the direction of travel (#3 above).
Spin Efficiency (aka True Spin) measures the amount of spin that contributes to a pitch’s movement. Both terms define the same measurement, but are displayed in two different formats. True spin is the raw value, for example: 1500 rpms.

In order to understand pitching data, you need to have a good understanding of a few basic concepts, including: 1. 1.1. Ball Movement 1.2. Magnus Force 1.3. Different Types of Spin 1.4. Gyro Spin 1.5. Baseball Spin Axis 1.6. True Spin and Spin Efficiency Ball Movement A deviation from a baseball’s trajectory from the time it’s released until it cro...
With all the basics behind us, now let’s go over where ball movement specifically comes from. There are two major components to ball movement, the amount of movement and the direction of movement. Here are the contributors to each: 1. 1.1. Amount of movement (“break”) 1.1.1. Velocity 1.1.1. Amount of True Spin 1.2. Direction of movement 1.2.1. Spin...
A lot of pitching folks talk about the real value in pitching data to be in the spin rate numbers. You often hear so and so has a curveball with a 3,000-rpm spin rate, or a fastball with 2,800 rpm spin rate. I totally disagree. Although it’s all great info, I believe that the most relevant information in the data is in the movement numbers and the ...
One of the most popular is spin. What exactly is spin in a golf shot? What should your spin rate be for your PW, 8 iron, 6 iron, 4 iron, hybrid, or driver be? How does spin translate into ball flight and shop shape? Below, we will look at the topic of spin—with per club break downs for your knowledge.
When we’re accounting for spin & movement, there are actually two types of spin on a ball; gyro spin and transverse spin. Transverse spin being spin with an axis that is perpendicular towards the target (the left picture).
Spin is defined as the rate of rotation of the golf ball when hit by a club. Spin rate is expressed in RPM and is measured about the golf ball's Axis of Rotation, regardless of the orientation of that axis. In a round of golf, every shot you hit is going to have backspin.
