Final vote for the location of the CIS-2017 tournament.

If you reason like that, then the opinion of those who say "I'll only come here" is more important than those who say "I'll go anywhere."

You and Merlin just did that. The opinion of someone who says "I'll only come here" is more important than those who say "I'll go anywhere."

Initially, the task was to determine the largest quorum. You can make it complicated with several rounds, which is what people are currently puzzled about.
Or, you could have conducted a normal vote with multiple choices and the question "Where can you go?"

With your system, if there are 12 people, they can come to points A, B, C, and they voted that way, i.e., points A, B, C will gather a quorum of 12 people. And there are 5 people who can only go to point D.
You and Merlin rigged the system so that point D would win.

That's what we're seeing now in the voting results. If there was a normal multiple-choice option, instead of the rigged "multiple-choice" you created, a person could have indicated that they could go to Yekaterinburg and Korolev. But now, their vote is devalued compared to someone who can only go to Volgograd.
So, in your system, "the opinion of those who say 'I'll only come here' is more important than those who say 'I'll go anywhere.'"

Well, that's all just a side note; I wasn't planning on going to Korolev after Vigo announced the prices. I only voted to support this circus.
