Just got a quick info regarding Hunter x Hunter for you today. The series takes about 2-3 times as long to translate as One Piece (the 2nd longest series in our weekly line-up), but at the same time, for many of us on the team, it's their favorite.
We have various systems of proofreading set up for all our series, ranging from simply reading through it while typesetting (putting the text into the bubbles) and making sure there aren't any typos to having a 2nd translator attached to a series who reads both, the raws and the primary translation fully - making sure no meaning is lost and often offering alternative phrasing options to the primary translator.
In the case of Hunter x Hunter, we have our most veteran translator working on the series, whose translations we generally only look through for typos and such and who makes those lightning-fast releases possible in the first place by staying up well into the early morning hours every week for us all. However, HxH is not an easy series to translate by any means. Not only is it extremely text-heavy, but often also worded very ambiguously, with complex grammar and vocabulary; especially so in the current arc where Togashi is throwing one complex scenario into the mix after another, along with dictionary-styled explanations for them all — leaving us feeling like Gon.
But as I mentioned above, it IS the staff's darling, so we go through extra lengths for it. We have several translators going through the chapters bubble by bubble, offering alternative readings. (For better understanding; Japanese often doesn't clarify who is talking to who or about who as pronouns tend to be omitted and/or unclear.) Given the length of the chapters and people involved, our goal is to have an updated, final, as-close-to-perfect-as-possible chapter that we're all very happy with by the following week. Thus, we highly recommend that you all re-read the previous week's chapter now before reading the current one.
For 350, we did the update already ~24h ago, about 2 days before the new chapter coming in, and we'll definitely try to do those updates asap, but generally speaking, re-reading it on Thursdays is your safest best. Let me know in the comments if you'd like facebook updates on that progress. To give you an idea, we updated 1-2 bubbles on about half the pages. While I wouldn't say that any of the changes affect the overall understanding of the chapter, most of them do contribute a lot to helping the dialog make more sense than previously. For instance, we changed the assumed speaker on 1-2 occasions, changed the implied (groups of) people in some other bubbles and improved the overall flow in everything else. In short: It's definitely worth re-reading, especially if you want to be sure that you have the most complete understanding of what happened.
Finally, I just wanted to state - those complex, difficult and often rambling bubbles are most definitely INTENDED to be difficult to understand, they're meant to look long and complex, and we aren't fans of removing that aspect in the translation by just summarizing what it says. We're meant to feel like this and enjoy it.
