Kinematic Sequence Analysis

250 Milliseconds.
5 Segments. 1 Chain.

Your entire downswing fires in a quarter-second. Each body segment must peak 20–50ms apart — faster than you can feel. Can you really diagnose what you can't perceive?

THE KINEMATIC SEQUENCE

Five peaks. Twenty milliseconds apart.

During the downswing, each body segment accelerates, peaks, then decelerates — transferring energy to the next. The timing between peaks determines everything.

ENERGY LOSS

15 milliseconds off. 30 yards lost.

When segments overlap or fire out of order, energy leaks instead of transfers. You can't feel 15ms — but the ball can.

SENSOR PRECISION

±9ms precision.
Not ±33ms guessing.

Cameras at 30fps have 33ms between frames — longer than the gap between segment peaks. Our IMU sensors capture at 1666Hz, resolving timing differences invisible to video.

Reveals the WHY

The gap between segment peaks is 20-50ms. At 30fps, a camera captures one frame in that window. Our IMU captures 33-83 data points.
