I vote in it but yeah, 5 is too much, and doesn't match wsj which was part of the fun of the idea for me. When there's 3 series there's usually a couple obvious top chapters of the week, then the 3rd is a harder choice I need to think about. But with 5 options I just end up shoving the usual favourites in each week instead of having to consider which had the best chapter. The fun of narrowing down the best and comparing chapters isn't really there any more.
The lack of being able to actually talk about why some series did better is probably part of it too, what's the point of a poll if you can't really talk about the poll?
Honestly maybe we need a general current spoilers for all wsj manga thread if we want to compare chapters properly (not just for this poll it'd be useful in general), one linked in the stickied post with the poll perhaps to make it convenient to get to.
The entire poll dont match Shonen Jump, here things are a direct reflection of votes, we know the votes, the toc dont even reflect who had the most or less votes, its a collection of things considered.
The 5 votes is made to allow few more choices for who read many or almost the entire magazine, also to make the polls more diverse since voting only on 3 will make people do exactly what you're saying, vote in the same locked series since they will not want to see their favorite series potentially in the bottom.
But after Buranchi started to discount the votes, going back to 3 would probably cause a big negative impact, even with 5 votes the overall number of votes the top 5 gets is already low compared to before because the excluded votes, with only 3 the numbers would drop even more.
About the discussion thing i agree that could at least be more flexible
