Weighting Factors for the Benchmark Conditions - 2001

The rankings under the five benchmark conditions were weighted before being summed to get a composite rank.  This was necessary in order to preserve the relative importance of each benchmark condition.  The Second Benchmark Condition (first serve at 110 mph) produced the largest values under the evaluation criteria, while the Third and Fourth Benchmark Conditions produced the smallest values.  Weighting factors for each evaluation criterion  were obtained by calculating the ratio of the best value for that criterion under each benchmark condition to the best value for that criterion under the Second Benchmark Condition.  Thus, for example, Torque under the First Benchmark Condition (forehand) was weighted 0.79 because the lowest Torque value there was 0.79 times the lowest Torque value under the Second Benchmark Condition, while Shoulder Pull of the best under the Third Benchmark Condition (volley) was only 5% of the Shoulder Pull of the best under the Second Benchmark Condition (110 mph serve).  Impact Force and Impulse Reaction were exactly the same rankings.
