We can try, but any participant in the Tournament should have the right to challenge the decision of the committee by providing a better Walkthrough, for example, within a certain period after the official results are announced. But based on the experience of previous stages, such a committee will not be particularly needed.
And as for the fact that the committee is not needed – is that really a problem... no budget money needs to be allocated for the committee meeting ;)
Here, a simple vote is completely inappropriate. To objectively cast your vote, you need to constantly participate in Tournaments or their organization, carefully study the behavior of various systems in various cases, etc., and not just anyone who comes in and clicks. It would be better to organize an expanded committee (about 15 people), discuss it, and then vote. Then it will make sense for those who want to form their own views on the system and present it to a fair assembly.
