The Power Threshold Array.
Seven Seats, each a Power and a Time Offset. How Raceproof reads a Seat, how a Seat moves, and what it cannot see.
A Seat is a threshold.Written as a Power and a Time Offset, how long the threshold lasts.
Power and Time Offset can move independently.One rider's PT-V over the year to October 12, 2026: Power on top, Time Offset below.
One race moves a Seat a little.A 75-minute virtual race on June 26, 2026, read through PT-G.
Seven Seats.From a sprint's first seconds to threshold efforts that run for many minutes.
WHAT THE INSTRUMENT CANNOT SEE
A Seat needs evidence before it moves.
Raceproof reads only what your riding demonstrates, so a Seat you have not ridden near lately gets little new evidence and drifts as the older work behind it loses weight. A quiet month erodes a Seat a little at a time. Nothing falls at once.
One ride moves a Seat a little, and after a long break the first rides back carry more weight, because there is less recent work to weigh them against.
Record a ride on two devices.Raceproof makes one record from both: a Fusion.
