Attack Angle – is the angle of the bat’s path, at impact, relative to horizontal. A positive value indicates swinging up, and a negative value indicates swinging down, where zero is perfectly level.

Bat Speed – is the observed speed of the sweet spot of the bat at impact. The sweet spot of the bat is measured six inches from the tip of the bat.

Blast Factor – is a holistic swing score between 0 and 100. It’s a weighted average of the other scored metrics with the following contribution:

Blast Factor is a convenient measuring stick for tracking your overall improvement and it’s a fun way to compare your swing to professionals, other teammates, or friends.

Power – The average Power generated during the swing is found from the effective mass of the bat, the Bat Speed at impact, and the average acceleration during the downswing. Power is measured in Watts. Higher Power is achieved when a hitter is able to swing a heavier bat and accelerate it to higher speeds.

Plane Score – Scores your on plane efficiency for each swing on a scale of 0-100. Your score is based on how you compared to others at your level of play.  The higher the score the better.

On-Plane Efficiency – Measures the percentage of your swing where the bat is on the swing plane. Your vertical bat angle at contact establishes the plane for that swing. Plane is a great indicator of making consistent contact and barreling balls.

Rotation Score – Scores your Rotational Acceleration for each swing, on a scale of 0-100.  Your score is based on where you fall versus others at your level of play. The higher the score the better.

Rotational Acceleration – Rotational Acceleration measures how quickly your bat accelerates into the swing plane. Rotational Acceleration is a good indicator of how you build bat speed by sequencing properly vs. pulling the bat with your hands. The quicker your rotational acceleration, the more power you will have and the more time you have to make a decision at the plate.

Connection Score – Scores how connected your swing is on a scale of 0-100. Connection is based on your body tilt and your vertical bat angle. The higher the score the better.

Early Connection – Early Connection measures the relationship between your body tilt and vertical bat angle at the start of the downswing. Establishing good connection (90 degrees) early in the swing helps you get on plane and increases your ability to adjust to all pitch locations.

Connection at Impact – Connection at impact measures the relationship between your body tilt and vertical bat angle at impact. Maintaining good connection (90 degrees) for all pitch locations is an indicator of dynamic adjustability.

Peak Hand Speed – is the observed maximum speed as measured on the handle of the bat (measured six inches from the knob of the bat). Peak Hand Speed will occur prior to the moment of impact, very close to the commit time in the swing when the wrists unhinge.

Vertical Bat Angle – is the angle of the bat with respect to horizontal at the moment of impact. Vertical Bat Angle is measured in degrees and provides the location of the barrel of the bat relative to the knob of the bat at impact. Vertical Bat Angle will be zero when the barrel of the bat and the knob are parallel to the ground. Vertical Bat Angle will be negative when the barrel of the bat is below the knob of the bat at impact.

Time to Contact–  is the elapsed time between start of downswing and impact. The start of downswing uses an advanced algorithm to detect when functional forward Bat Speed is initiated and is not triggered by bat waggle early in the swing.
