Example Calls

Show me detailed lap times for that Formula Vee session

analyze(analyzers='lapstats', event='01H8SP4HK4')

Displays all lap times with statistics including best, worst, average, and consistency

What were my 10 best laps

analyze(analyzers='lapstats', event='01H8SP4HK4', lap_selection='best', n_best_laps=10)

Shows only the top 10 fastest laps with detailed statistics

How consistent were my lap times today

analyze(analyzers='lapstats', after='2023-08-26', lap_selection='all')

Analyzes all laps to show consistency metrics (std dev, coefficient of variation)
