"you can engage the car in more understeer/oversteer before PSM kicks in"
Yes, one could argue that delaying PSM improves performance. But in my experience couple of weekends ago and in the rain, the timing was just right the couple of times it turned itself on. Had PSM switched on any later my performance would have decreased quite a bit -- smth like the two GT3s' that got mashed pretty bad after skidding out.
