It makes no difference how they throw compared to others. The bottom line is that for most they are unable to throw at all unless they do so illegally. In the case of Miss Barnhill when she does throw legally it is substantially slower than when she leaps.
I agree and really wasn't very clear during my posting on this. Just trying to make the point to stay on task (the legal task) and your DD will reach higher than those who do it illegally. It is tempting (at least it has been for me) to teach a replant but I haven't and won't because the Jake's of the world who do it right have found themselves leading their D1 schools to victory. They are the role models I want my DD to follow.
