I have a theory a little different from (bonus points), my theory is that there is no bonus point and if there is it is very small then I think that in danmachi the points of a level are worth at that level, but in other levels it decreases (based on what loki says in SO." higher level stats are worth more than lower levels" ), example:

•level 1: -100 points at level 1

•level 2: -100 points at level 1 are worth 50 at level 2 -100 points level 2

•level 3: - 100 points at level 2 are worth 50 points at level 3

what I'm trying to say is that a certain amount of points from a level 1 are worth less in the next levels because I think, 0 everything when you level up and the past statistics are inherited as a base and taking into account that in the series they always refer the flaw as a type of container and also a stat point at level 1 cannot be gained in the same difficulty at level 2, everything leads to believe that if you have bonus points and a low amount like 100 points more in each stat when going up of level and the difference in quality in the excellence of a level 1 and 2. this also explains why ryu went up 2 levels in vol.18 because thinking that the limit is 999 and difficult fights with risk of death and fights between humans (or other species created by the gods like elves and dwarves) give high-level excelia, and having surpassed the amount of base stat one can have in a level, the same excelle gained in excess level 4 can be passed to the next level, and as ryu it was already a level 4 with several high status and with the various battles in the time that the statuses did not update, making it possible to achieve achievements above your level (battle against jugernaut) that made it possible to go to level 6.

what do you think of this theory in which I try to explain about the level and the statuses and their possible relationship with the status bonuses?
