Introducing Gain Factors! – which are derived from the Kinematic Sequence.
Gain Factors measure how much speed is added between body parts in the swing. For example, Core Gain Factor looks at the speed increase from the pelvis to the chest, Shoulder Gain Factor checks the speed from the chest to the arm, and Wrist Gain Factor examines the speed from the arm to the club. By comparing these factors to optimal values, we can pinpoint areas in the swing where golfers might be losing power. With this information, we can help golfers focus on specific body parts to strengthen or improve in order to gain clubhead speed.
- Core speed gain factor: The ratio of the max chest turn speed to the max pelvis turn speed. (Pro-Driver: men's avg.= 1.5, women's avg.= 1.4)
- Shoulder speed gain factor: The ratio of the max lead arm swing speed to the max chest turn speed. (Pro-Driver: men's avg.= 1.4, women's avg.= 1.3)
- Wrist speed gain factor: The ratio of the max shaft swing speed to the max lead arm swing speed. (Pro-Driver: men's avg.= 2.3, women's avg.= 2.0)
- Release factor: The ratio of the max club head speed to the max hand speed. (Pro-Driver: men's avg.= 5.0, women's avg.= 4.8). **This is like Sportsbox’s equivalent to the Smash Factor**
- To populate Gain Factors, swings MUST BE RECORDED IN-APP; imported swing videos will not work (nor will previously imported videos).
- Make sure the recording is in a space with good lighting (preferably outdoors, not backlit) – won’t generate accurate numbers if you’re in a dark indoor space or too bright outdoors and have to use the “extreme lighting mode” feature to record.
Gain Factors are only available for Pro Premium and Enterprise subscribers; they are not included in the Pro Lite plan. If you'd like to upgrade, please contact us.
