I'm seeing the setting is like NG+ with MC starting at lv1 but with max stats that can still grow again from lv1 despite the growth rate is not great. So it's like: i.e.
Lv1 Talented mages = 10 base stats + really high growth rate +10/lv, 1000 at lvMax
Lv1 MC now = 600+6 base stats (because he never reached the peak where talented mages could) + moderate growth rate +6/lv, 600+600 at lvMax.
Personal rant:
On one hand, some readers want the chapters to be caught up as the latest update, on the other hand, some readers want each chapter to be accumulated fully only to be then scanlated and released, in the end it's like Scanlation groups can't win because it's either one way or another so one side would surely complain and demand their way... It's not like the groups scanlate 24/7 or purposely scanlate poorly to troll readers, they are people with a life not tools.
Rationally, releasing chapter in parts according to the official release arrangement/schedule is just making more sense for me because if one wants to read a chapter in full they could have just put the chapter parts on hold until it's full only then read it (which is what I do for some mangas), the Scanlation groups are really not forcing anyone to read them in parts if the readers don't want to.
Anyway, thanks for picking this series up and great job, Kirei Cake!
