I mean, Kimetsu always placed well in surveys from debut. This was mentioned in one of the interviews. I dunno about Act Age or Sket Dance. World Trigger, which everyone thought initially did badly was also revealed that have done well in surveys.
This is just you playing naive as if you can't see how much obviously different is the Shonen Jump of Nakano (and current industry state) compared to other years specially the Jump from the 80's and 90's, ofc we will still have series like Zipman that end fast, this happens with every magazine when a manga is a blatant flop (Buddy Strike was from 5 years ago), but i don't know how much obvious things can be when we have the the Taisei, TSS and BC trio surviving for 27 chapters selling like shit, Kamio Yui going for 36 chapters with 5k, Mitama surviving even more with 5k, Yozakura, Undead and Agravity being considered as decent to good receptions with 10k/15k, things that would really not happen some years ago.
Kimetsu was not a low ranker. It ranked top 3 twice within its first 10 rankings, got CPs in chapter 7 and 16, and only ranked bottom 5 twice in its first 20 rankings. Its lowest ranking over 205 chapters was a bottom 3 and it only happened once, and not even in its first chapters (chapter 38/31st ranking). Sket dance just fit the role of gag manga that jump likes to place at the bottom, while act-age is...indeed a weird case. The exception that proves the rule, if you will.
Who's talking about sales? The former editor in chief is entirely talking about reader surveys there. Mitama is probably doing fairly well on reader surveys judging by it's ToC position (since sales certainly aren't putting it at #5), and I remember Yui Kamio often doing passably too hanging around the edge of the bottom 5 a lot rather than right at the bottom. Agravity Boys certainly is not considered to have decent to good reception since it's dead last, and has been bottom 3 most of the time.
It is clear that sales are as important as Toc, after all it is money that also goes into the pocket of the jump.
You're not making any sense, sales have everything to do with a series surviving and is totally correlated to how a series is placed in the "ToC" since this is just placements decided by a group of factors including volume sales, i still don't know why you treat the "surveys" thing as if is a entity by itself when everybody knows that these placements aren't even a 1:1 of the "survey results", you also have this tendency of treating the ToC as a ruler when it comes to overal reception, when is just a little bubble inside Jump, there's a entire population that doesn't buy Jump or don't care about surveys and buy manga in volumes, this is the real "reception", not some people filling a survey, Agravity Boys for example had a great reception and great reviews for volume 1, getting a reprint and mention in radio shows but you just try to focus in "ToC placements" as if that is the ultimate japanese reception for mangas.
While samurai 8 sales were not bad, it was way below what was expected for a series made by someone as famous as kishimoto + the added advertising push it got before hand. Correct me if I am wrong it had with declining sales from volume to volume with Vol 4 selling 14000+ in 5 days. Contrast that with Kimetsu Vol 4 which sold 20000+ in 3 days
Sales are also important, jump is not a charity. you can put all the examples you want more if sales were not important so it is not worth buying volumes.
RxL sales where declining with each volume, as a company, keeping a product that cant grow isnt worth it, the same was with S8, the costs of publicity, a probably expensive Kishimoto contract and being a not growing series caused that. It isnt about "this series sold more than this ones and still got axed" but about how profitable the series can be in the future, which in both cases, it showed being series with no growth future.
May I see the article where the EiC says that they cancel series based on reader survey results? I'd like to read that.
It's the one I posted earlier, from an interview with the former EiC but still seems pretty relevant even if some things are different now, since we still see some new flops starting building to the ending around ch 10.
Look at Act-Age wiping the floor with many other series. I think I really should read it.
lol You're just straight up being contradictory, if Agravity Boys have decent sales, good reviews aka reception, gets a reprint by Shonen Jump itself, how Shonen Jump don't consider it to be well received or worth pushing when they already did?
