I haven't read 11 yet, but there are more things to consider than this being "Chapter 11". Each chapter is this series is quite big, for example the first chapter was around 90 pages and the second one about 70 pages, so there's a ton of content in each chapter. What also helps matters is that the main character is quite impulsive... I myself like the current pace, but you have to keep in mind that these are not normal chapter lenghts either. It comes out in Shonen Sirius, which is a monthly magazine if not mistaken.
