Eight sections. Where to look first.
Equal-distance windows, not named corners. Click to inspect; positive values are losses.
Measured review queue
Ranked positive section deltas above 0.10 s. A review filter, not a GPS precision claim.
Speed differences: selected minus reference. Minimum values may occur at different positions; “exit” means the section boundary, not a corner exit. Missing samples suppress mean/minimum.
Repeatability & reference
All complete laps in the selected session; traffic and slow laps are not filtered out. Spread = slowest − fastest.
