Nobody prepared to hazard an opinion on the three contentious scenarios I proffered?
There is disagreement between various national unions. Some say it is the body that counts, other say the feet. It is a split second things anyway, so it is hard to be very precise. Personally I simply judge the torso - but then I am not making the decision. I might discuss the question with a referee but as long as his answer is sensible I am satisfied. It is too rare to make a fuss about.
