Confused About Armor Xp Bonus

So im trying to grind xp im lvl 37 but i dont understand if i should use an armor piece that gives a 15% xp bonus or if i should use another that gives a 10%**

TL:DR what does the x's at the end of %'s mean/do

 

Im pretty sure the calculation of armor xp is: "The xp you get from mobs" + ( "The xp you get from mobs" X armor xp percentage )

Also the star symbols next to the stats just mean how close to the max it is (out of 3 stars)

 

When a stat (Identification) has got a star, that means that it got a good roll. When you Identificate an item every stat gets a roll. From 1% to 100%. Sometimes IDs do not get 100 variations in possible rolls but the roll is still 100%. So you can get a 1/4s Mana Regen ID with 3 stars but one with 0 stars would still be the same because 1 is the max amount anyways. So an item which has got 10% bonus with 2 stars is likely to be maxed at 10% with only a maybe 90% roll. The amount of stars next to an ID does not change the ID itself. Don't care about stars that much. When an item with 15% XP bonus has 0 stars but a different item eith 10% has 2 stars, the 15% is still greater. The stars dont matter in that case.


I am not good at explaining but I hope you got what I was trying to say.

 

When an item is identified, every identification gets a score from 1-100. The higher the score, the better the identification.
The astarisks signal how close to 100 that id's score is. 100 is 3 astarisks (I think) 90+ is 2 astarisks and I don't remember how much 1 astarisk was.

However, if an item has a higher base identification (such as an item that has a 30% xp base) it can go higher than one with a lower base id (such as one with a 10% xp base) even if the id with the lower base gets a higher score.
