So, if I understand correctly, the argument about 1/3 for Volgograd included Merlin (6) + IDD (6) + Oxygen (6) = 18 / 49.5 = 36.3% of Volgograd's total.
For Yekaterinburg, by analogy, it's Mee (5) + Asm (5) + for example, Katya (3) = 13 / 36.4 = 35.7% of Yekaterinburg's total.
Yekaterinburg: 13 points (5 times a player)
Volgograd: 18 points (3.5 times a player)
Total points: 49.5 + 36.4 = 85.9
Therefore, we get:
Yekaterinburg: 13/85.9 * 100 = 15.13% (5 times a player)
Volgograd: 18/85.9 * 100 = 20.95% (3.5 times a player)
And simply put, 18 > 13 by 5 points (that's 38%).
This is how we get a higher weight of votes with a smaller "player" coefficient.
