Football evolves. And in the search for its improvement it is nourished by any discipline. Also of mathematics and economics. Thus, UEFA, based on a study of Spanish teachers Ignacio Palacios-Huerta and Jose Apesteguia , is planning to modify the development of the penalty shootings. And it will prove it in the current sub 17 tournaments being held in Croatia (male) and Czech (female).
The model of five alternative releases has become obsolete and more justice is sought. This way it would go from launching with the traditional ABAB model to doing it with the ABBA that govern the tie break in tennis. The new sequence will alternate the one that starts to throw in each block and, according to the UEFA explains, would be done as follows: AB BA AB AB AB . If all five pitches are equal, the sequence BA AB BA … will be followed until there is a fault.
The Next Revolution in football
The highest body of European football crystallized a research published in 2010 by Palacios-Huerta and Apesteguia, professor at the London School of Economics and Professor at Pompeu Fabra, respectively. It was in the American Economic Review. After analyzing around 2,900 penalties in 270 batches launched between 1970 and 2008, both concluded that with the traditional pitching system, the opening round has a 21% chance of winning the batch, and the match, than its rival .
The study, which later also affected possible advantages of playing black and white chess, was presented to FIFA, UEFA, RFEF and European and Spanish Chess Federation.
The new order seeks a more equitable development, divide the batches into small blocks and change the order of the pitchers. The theory of Palacios-Huerta and Apesteguia reveals that with the current system open tanda has an advantage.“The currency also plays, the effect is so great that the most decisive moment of a batch occurs in the launching of the currency,” said the professor of Biscay at the presentation of his report in 2010. Before being approved, International Board.
