Bands and Chains Wreck Your VBT Velocity Readings: How to Fix It
Add bands or chains and your velocity zones lie. See why accommodating resistance skews VBT readings, and how to test and prescribe around it.
Bluetooth Dropout Losing VBT Reps Mid-Set: How to Diagnose and Fix It
A set logs 4 of 6 reps and the velocity chart has a gap. Split the cause into interference, distance and buffering, then recover the missing data.
Linear Position Transducer Cable-Angle Error Fix: Correcting Off-Vertical Pull
An off-vertical LPT cable inflates displacement and velocity readings. See why, how to test your setup, and the mount fix that corrects it for good.
Fixing 2D Perspective Error in Video Barbell Velocity Readings
Camera angle and bar depth drift can throw off video velocity readings by 5-15%. See the geometry behind the error and how to correct your camera setup.
Fixing Bar Velocity Spikes From Bouncing: How to Spot and Filter the Artifact
A single rep reads 1.4 m/s and wrecks your average. Learn why bounced reps and bar drops spike bar velocity readings, and how to filter the artifact out.
Fixing Deadlift Velocity Shifts From Grip Style: Standardizing Hook, Mixed and Strap Pulls
Switch from straps to hook grip and initial pull velocity jumps 15%? That is grip mechanics, not new strength. Here is how to standardize the reading.
Estimated 1RM Keeps Changing Daily: Is It Noise or Real Readiness Drift?
Your velocity 1RM swings 8kg between sessions with nothing changed. Separate measurement noise from real readiness drift and build a stable baseline.
When Smith Machine Counterweights Skew Velocity Readings: How to Correct for the True Effective Load
A counterbalanced Smith machine quietly subtracts kilograms from your real load. Learn to measure the offset and stop it from wrecking your velocity zones.
Why the First Warm-Up Rep's Velocity Is Noisy and Should Be Cut From Your Load-Velocity Regression
The opening warm-up rep runs slower than rep two or three. Here is the neuromuscular reason, the data behind it, and how to fix your load-velocity line.
Rising Velocity Mid-Block: Real Gain or Artifact?
Velocity climbing at the same load mid-block? A checklist for telling real strength adaptation apart from technique cleanup and plain measurement noise.
When VBT Velocity Jumps After Caffeine: Reading It Right
A caffeine-driven bar speed jump isn't a strength gain. How to separate stimulant-driven VBT velocity spikes from a real 1RM improvement, with numbers.
Why a Two-Load LV Profile Gives You the Wrong 1RM
A two-load velocity profile can be off by 10-20% on your 1RM when the loads sit too close together or bunch at one end. Here's why - and the fix.
