Gradient Selection Threshold
Define the maximum absolute grade percentage to categorize as “flat” terrain. Recalculates speeds across all loaded files.
Consolidated Historical Baselines
Weighted mathematical average across all loaded files
Calculated solely from points with grade ≤ ±1.0%
Calculated solely from points with grade > ±1.0%
Calculated solely from points with grade < ±1.0%
Velocity Baselines by Ride / Rider
Overall average speed compared against isolated flat-ground average speed
Terrain Composition
Percentage of distance spent in each grade zone across the datasets
Comparison Matrix
Decoded sensor outputs and computed averages on isolated flat terrain segments
