Trying to figure out how to interpret this too. I'm currently at 150. I dont think you need a full set of t13 +9s for 153. I have a +9 weapon, +7 feet. Then other 2 pieces are t12. So far it looks like 153 should hit ~ 3 t13 +8/9s.
Rings are the big thing dragging everyone down.
Unless I missed something and there are ilvl 146 or better rings...
Isn't iLevel just an average of all the items?
Hemm... the easiest way to test would be to take out each individual item and see the GS change
That will let you know the weight placed on that item.
E.g. let say you have score of 185
You take out lancer (with score of 188) and it drops to 170
that means your 188 is translated to a score of 15, so it has a weight of 7.9%
Just do that for each and you will have the basic ratio. If the weight is not linear then you have a problem.
