Voting for the location of the CIS-2107 tournament.

If we compare percentages, then it's better to calculate based on the total scores:
Ekaterinburg: 13 points (5 times a player)
Volgograd: 18 points (3.5 times a player)
Total points: 49.5 + 36.4 = 85.9
Therefore:
Ekaterinburg: 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 is greater than 13 by 5 points (that's 38%)
That's how we get that the weight of the votes is greater with a smaller "player" coefficient.
