i'd just like to point out that laptimes may be useless for a novice, but having their line maped by gps, along with ecu imputs such as brake and throttle pressure would provide for extreamly accelerated learning if done correctly by an isntructor.

nothing says you're braking too early or late than a graph that is actually showing you where and how hard you are braking

improved tenfold if a few control laps are done by your instructor beforehand.

proper datalogging should have been the first thing i invested into back when i started to drive, sadly it's taken me many years to realize how much learning opporunity i've missed out on over the last decade.
