I dont mash the throttle on exits but rather try to feel for rear traction progressively and yaw dependent. Even when in Race which still has TC. And clearly not with all off. Perhaps thats not the very fastest way but i dont want to learn bad habits as i drive other cars sometimes.
But i do believe the TC will retard throttle accordingly if one just floors it at the apex. But i dont really see much point in recommending such technique as proper, even if automation can deal with it.
I mark the start/finish on PDR every time i go out. Unsure if it remembers a specific venue a la other GPS timers. Perhaps somebody else can chime in and help us both.
Ps that ride in the historic car must have been uner fun
Cheers!
