No what im looking for is the equation thats used as in, there has to be an equation that that gives you the outcome of what chance you have to get a certian item such as a windforce. His calc lets you enter a few variables, and then it gives you your % chance on getting the item you chose. This also includes magic, rare, set and unique. I just need the equation or "algorithim" he used to get the answer. An example would be like.
chancetogetitem = itemrarity/mf * 2
Thats just an equation I made up and probably isnt even close to the equation he uses. But I do know it depends on these variables.
your mf %
the item level
item quality - as in "rare, magic, set, unique"
mlvl - "monster level"
number of players in game
Here is a link to the calc I am getting this from.

Its the item search one, maybe that will help to better explain what I need.
