How to kick a penalty...scientifically

[Karl]

i cant see anyone who could replicate this each time. not only that...doesn't the goalie know where the ball is going to go if yopu keep doing that?

what about the wing span of the goalie?

If the refs enforce the "Law" that cannot be saved. Matters not if the goalkeeper knows that is where the kick is going. Truth is even if the ref's do nto enforce the "Law" such a kick is just about impossible to save. (...perhaps a 7+' goalkeeper with good jumping ability and great agility?)

Another of those errors refs too often make - Allowing the goalkeeper to move before the ball is kicked...and when a save is made or the kicker misses...not following the "law" and having the kick re-taken.

This error has become the norm. I suppose a ref would risk life and limb if he dares to have a retake after a miss.

NB: If the kicker scores when the goalkeeper flouts the "Law" by 'moving early' the goal should stand.

Scientists have come up with a formula for taking penalties that, if followed correctly, has a 100% success rate. The shot should be 65mph, you need a run-up of five to six paces from the edge of the area, approach the ball at an angle of 20 to 30 degrees and the ball must cross the goal-line at exactly 0.5m below the crossbar and the same distance inside the post.

If the keeper can move on his line before a penalty is taken I cannot see how this information can be accurate
