Despite the differentiation between the categories of master I (40-49 years), master II (50-59 years), master III (60-69 years) and master IV (+70), the formula for obtaining the wilks can be inefficient for calculating the score in the master's age categories. From this need for adjustment, the McCulloch coefficient was created, which scores older athletes upwards.
To apply the coefficient, it is enough to multiply the weight lifted by the coefficient associated with the age of the athlete, causing a theoretical increase in the weight lifted. The result is then used for the wilks calculation.
