I have a spread sheat to that system but I cant find the link to his post.
Here is the link to a (german) page where you can dl the excel sheat:

PS.: I forgot to add he didnt calculate the weapon dps in I think the Weapon ilvl arent correctly calculated. Because you can get points when you make the item go to a lower dps then it would have with it itemlvl (for examble azuresong blade has only 40 dps it should have a much higher dps according to its item lvl but it has more stats instead)
