Point taken and I did place a note on the top of the Game Items part that says as much to better explain this to the users of this page. I have yet to be able to find the Item success rate or the luck rate so I can not give examples for this note.

I think it is defaulted in the game based on something about the item itself. But no way to prove this since it seems to be Server side calculations or Hard Coded into the Client itself.

And there's also the probability that the developers hardcode placebo codes to screw us over. If only they used more precise English in their description, we'd be sure if the numbers are additive or multiplicative.
