Mobs' drop rate (% chance)

[Ovid 17]

Hello.

If somebody can explain to me how the drop rate works, I would really appreciate it. 

I know that the higher your level and the lower the mob's level, the chance and amount is lower.

But how is it possible to get a full weapon drop from a green mob (1/10'000 chance) and not get a spell book drop from a white mob (1/2'000 chance)? Why do I get more drops from a light blue mob than from a green mob?

Is the drop chance information from https://l2db.club/?show=item_info&id=49432 correct? Is the server's drop rate correct?

I know that post, but it doesn't really answer my question about the mob color.

I know that in Lineage 2 the color of the mob can influence the chance of dropping stuff (either adena, parts, mats or full items). I am experiencing light blue mobs dropping more often than green mobs.

I think in Classic drop rate from white, green and light blue mobs has no difference or changes very slightly. But it's just my pov out of own experience.
