While cameras guess at 30fps, our IMU sensors capture 1,666 data points every second. That's 55x more temporal resolution. The difference between seeing a blur and seeing the truth.
TEMPORAL RESOLUTION
A full downswing takes ~250ms. Here's what each technology captures in that window:
33ms between each frame
Still can't see muscles
0.6ms between samples
THE MATH
At 30fps, a camera might capture ONE frame during the critical timing window between segment peaks. Our IMU captures 33–83 data points in that same window. That's the difference between "it looked fast" and "your pelvis peaked 12ms before your thorax."
WHAT HIGH-FREQUENCY REVEALS
With 1666Hz resolution, we can detect timing differences of ±9ms. That's the precision needed to diagnose kinematic sequence problems.
Know exactly when segments overlap instead of sequencing properly. 10ms difference = visible in our data.
Pinpoint the exact millisecond each segment reaches maximum angular velocity. Miss the peak = miss the transfer.
See if segments decelerate before the next one accelerates — the hallmark of efficient energy transfer.
Compare timing gaps across swings. A consistent kinematic sequence = a repeatable swing.
