Looking for drop charts (Skyly)

Are you saying that you find 1/21 is more misleading than 4.762%? I still don't see how it can be

Simple. 1/21 implies if only vaguely) that one might find a rare item with this particular drop rate once in every 21 appearances of the enemy that drops it... Naturally I won't believe that for a second.
However to the untrained eye, or to the eye of the unaware, this may be the case.
I'm just saying that I think a percentage may well clear up any imperfections.
And on the 4.762% thing, I see it as something like 4.76190%. Notice the 0 is preserved, if only to avoid upper- and lower-bound confusion.
