That's a huge boost for Saki Achiga-hen. It's up 53k in week one over what the first volume did in two weeks. Original Saki has a pretty good boost as well. Could get higher depending on second week numbers.
YES! Volume 41 has long been anticipated by the fans, and it's so nice to see it on this list, even if it's low. I simply can't wait until Chaung Yi finishes translating the remaining 2 volumes of the Diamond/Pearl/Platinum Arc so they can get started on 41, which brings back the Johto 'dex holders with the new HeartGold/SoulSilver arc!
