I have two slow motion videos; of Brian Gay and Greg Norman where the hips actually counter torque and turn back away from the target a few degrees before Impact. So, it's possible to witness this event on Video. I'll find them and put them up for everyone's review.

This would be great to see if you have these videos, looking forward to seeing them, with stock standard cameras you can't pick this up when you slow them down. If your breaking down a golf swing frame by frame in slow motion, supper stiffen is something you miss. Super stiffen and impact can occur between frames.
Depends on what people class as impact. I'm talking about when the ball and clubs very first contact when to ball and impact initially come in contact, or exactly moment super stiffen occurs.
Do you know what frames per second between 5000 to 10000 frames per second? Must have been captured by some very high tech gear. Or extremely lucky it occurred in sequence to frames. A very rear occasion.
