Yes it wouldn’t be 50/50, that would give the average WLer even more voting power than the roster nations
But with this system, we could adjust the proportioning to anything: from each WLer’s votes counting fully; it equalling one voter’s worth (similar to how it is now); Or something in between.
An advantage is that everyone’s votes will count in some way because the final total is not bound by the top ten. I think you could still fall victim to that in the cohort system depending on who your cohort-mates are. Whereas this just totals up every vote from every WLer.
To illustrate my potential vision, here’s NSC 193’s total WLevote,
In the event that we want WL votes to each count 100%, then we add this televote score as it is.
If we want it to count the same as we have until now, but just represent everyone’s votes better, then we proportion it. 18 nations voted, so dividing by 18 would make it count as one nation’s worth. I don’t think this is particularly fair or interesting as the highest score would just be 4 points.
So we could adapt the cohort idea and meet in the middle by roughly having the WL represent, let’s say, 6 nations’ worth. Dividing the total scores by 3 would then make it count as 6 nations’ worth etc.
Here’s the 6-nations’-worth WLevote (scores are rounded to the nearest multiple of 3)
Which weighting we go for would be subject to a poll vote.
