). But there have been instances where Jump seems to have done what would seem very silly from a business point of view. Who knows if they will do it again? As fans, we can just hope Mago tides over this rough patch ranking-wise. Having read the recent chapters (esp 143) I think there is much hope for the series to pick itself up on the TOC 
I just caught up to reading Mago, man I hope it doesn't get cancelled.The topic of whether or not Jump considers tankoubon sales or not when they bring up series for cancellation has been discussed tons of times in this thread (and its predecessors). The answer is that really, we don't know if Jump does consider tankoubon sales or not. There is evidence to point both ways, so there can be no conclusive verdict.
Yes, from a business point of view what Westlo has said is very true (in fact Mago sells >500k copies per volume on average
Anyway there is really no point in debating over that, so let's put that to rest, shall we?
And I'd think that even if Mago is forced to end earlier than Shiibashi intended, they'll give him more time than they did Iwashiro for Psyren. At least I hope so.
That's some harsh words for series we haven't even gotten a chance to read yet...
Shueisha basically only makes money off tankobon sales. The magazine is a loss leader. Mago turns a profit for Shueisha, canceling it would be terrible business. The absolute worst case scenario for Mago is that they determine that Mago fans are not buying Weekly Jump and move it to SQ or Ultra Jump. D. Gray Man and ToRa are the best comparison. Both sold about the same amount of copies as Mago, both floated around the bottom five, both were moved rather than canceled. The low ranking might not have much to do with how fans feel about the stories quality. I bet that Mago appeals to a slightly older audience. The vast majority of Jump readers are 15 or younger. Series with mostly older teen (16 and up) readers tend to poll poorly. Again, DGM and ToRa are examples. Death Note too. It always polled in the middle, never the top but never the bottom.
It's just a sad truth. Only two series made it out of 2010, and one of them is just getting by, so I imagine that 2011 will be just as rough.
Sket Dance, KHR and Mago are quite low this week. I'm impressed that Hokenshitsu has been persevering despite being in the bottom 5 for a while now. (I followed Aimoto on Twitter so I hope the best for her.) No problem, Prince! 2ch is at fault here. I feel it's about time Togashi should make a return since the hiatus has been going on for so long. (It's been nine months already?)
As I understood it from trends among other conversations and observations the counting is inclusive, so in your scenario chapter 100 would be ranked according to chapter 93's results.
The general consensus a little while back was that it would be ch. 93. It's the chapter 8 weeks ago, this is counting the current week, or ch. 100, as the first week. 100, 99, 98, 97, 96, 95, 94, 93. Hope that helps
Sigh...not it DOESN'T get weird with double issues as chapters are ranked based on 8 CHAPTERS not WEEKS. It makes ZERO SENSE to rank chapters by weeks for THIS VERY REASON.
