Traction control

Has anyone had any experience with the traction control settings on their 3 series?

Full on is pretty restrictive but single push DTC does allow quite a bit of wheel spin. I understand that this allows more wheel spin before power is cut and that the DSC will brake individual wheels if the car is going sideways too much thanks to steering wheel position and accelerometers and wheels speed measurements. The question is how much? On snow it was pretty easy to get sideways on DTC mode. Full off was a whole different level. DSC is off. Even moving away slowly on snow spins the wheels very easy with a feathered throttle.

Yesterday trying to do a WOT pull in 3rd gear (single push DTC mode) from ~2000 rpm had the car squirming around. I bet in full TC/DSC off I'd have been sideways and in the barrier looking like an idiot. I felt confident that DTC would keep me safe. Is that confidence misplaced? Have people had close shaves even in DTC mode?

Any track or closed road experimentation?

It must be very tricky going WOT with traction control fully off.
