Item Creation Confusion

[Jarulf]

From this it follows that the prefix or suffix with the lowest qlvl on an item can never be higher than half (rounded down except for Wirt and some Adria items) the qlvl of the higher one (the other way around the higher level can never be higher than 2 times the lower one, plus one if odd, (except for Wirt and some Adria items) the plus one due to rounding effects if the item does not come from Wirt or Adria).

I don't understand how that follows from the given formulae if they do, in fact, merely represent ranges of legal qlvl values for affixes generated by different sources.

I think there is a typo in my guide. From a quick look of your quote, I would say it should read:

...with the lowest qlvl on an item can never be LOWER than half (rounded down....


That would make better sense, no?
