typically its 1 CR (control rider) per 4-6 Novice riders.. and each class goes out in 20 mins sessions... last time with STT it was Intermediate went out first, then Advanced, then novice, this was done so the novice riders have time for their class room time after each session, this being a club day i dunno if they will have more CR's for novice or not.. they have CR's for each group just to make sure everyone is operating in a safe fashion
