both are wrong answers

The pic we see it's the only screen left in the game that shows the real quality of two teams (the q of current 11th squads).
The problem with that screen is that we don't know exactly how it calculates and compare the quality.
For example it considers the quality of the GK for defense q.
It considers the quality of a DMC in the defense and in the middle area.
It considers the quality of AMs in attack and in the mdf.
But we don't know how much - never explained.

Anyway, the calculation of adding those three qualities and then /3 is wrong.
