Example Calls

Where am I losing time at Spa

analyze(analyzers='cornering', track='Spa', lap_selection='best', sort_order='time_loss')

Analyzes best lap, ranks corners by time loss to show biggest opportunities

How consistent am I across all my laps in that session

analyze(analyzers='cornering', event='01H8SP4HK4', lap_selection='all')

Analyzes all laps to show consistency metrics (std dev, CV%) per corner

Show me my performance through Big Bend

analyze(analyzers='cornering', track='Lime Rock', corner_names=['big_bend'], sort_order='track_order')

Filters analysis to specific corner with sequential ordering
