So, to be clear, the term 'lift-off oversteer' is only ever applicable when the throttle is fully closed? A partial throttle closure does not ever count as lift-off oversteer? Is there a point where a partial throttle closure is counted as fully closed (95%, 99%, 99.9%)? I guess it's never fully closed because the lowest setting is when the engine is idling. I ask because understeer and oversteer are defined as turning less/more than the steering angle (and oversteer does not mean loss of control or the requirement for opposite lock), so while at steady state a partial lift will cause a mild weight transfer and mild oversteer, at least in the transient sense (because it will settle down given time to a constant turn radius when the longitudinal acceleration reaches zero), and a full lift will cause a larger weight transfer and greater oversteer (possibly, but not necessarily, resulting in a loss of rear traction). Loss of control I imagine is governed by the traction circle (how lateral and longitudinal grip interchange), so if you're on the edge of the traction circle laterally, then any longitudinal load will cause the circle's perimeter to be exceeded. The Wikipedia article mentions that throttle closure (full I guess, but it isn't explicit on this) has the potential to cause the car to swap ends, so by it stating 'potential', then this implies a sliding scale of possible responses from a tightening of line to going backwards. The drivingfast.net article talks of reducing the throttle to induce oversteer, not fully closing it. It also says that it can upset the balance enough to allow the rear wheels to break loose, so again a sliding scale of responses to a throttle lift. I think we're stuck in a semantic war of words, but I don't think people who say they want lift off oversteer want it so that they can spin.
