⚙️ Advanced Parameters

For experienced users — fine-tunes the physics model

Bike Physics

Crr and drivetrain efficiency affect all results. Use your measured values or accepted defaults.
Starting estimate (hint only)
Rolling resistance
0.03 = 3% (standard road bike)

Air Density

Auto-calculated from temperature, pressure and humidity. Applied automatically from weather when GPS is available.
Auto-updated from T / P / RH above

Analysis Settings

Higher = less noise
Offset alignment window
Positive = tailwind · Negative = headwind. Auto-filled from the wind assumption above, but you can override it here before analyzing.

Data Prefilter

Removes unreliable samples before fitting. Defaults handle the vast majority of rides.
