"originates from a global average that considers the values on the single skills (if sufficient numbers of skills are performed).
For the setter you have to consider, apart from the evaluation for the serve and the block, the positive attack percentage on a positive reception."
"is a number indicating how a player has performed during a game. All the skills are evaluated and have a specific weight assigned to them. It is acquired by plugging in the weight of skills into an elaborate formula, which compares an average of different weights of different quality of skills divided by the total number of hits."
I thought of whether it was the value of the critic in many ways.
Is there a source of a definition?
