As we can see, this is the 5 best chapter of Nisekoi according to Jump reader.
So what the TOC has to say about those 5 chapter ?
There is absolutly no correlation between all those chapter no matter the scale of measurement used.
Okay, that poll is not the most accurate thing ever and even and myself struggling to take it completely seriously (the chapter 97 is obviously the number one because of Y-san), but it's from my point of view the most unbiased link between the TOC and the actual popularity of a chapter in the Jump that we have today.
So until a new progress on the subject, their is no direct correlation between the TOC and the poll result, maybe a medium term correlation exist but that's all.
