+# Finding HQ values
+
+HQ values are just the difference, the "additional number", if an item is Accuracy: 32, and HQ Accuracy: 35, the HQ value is listed as 3.
+
+An example can be found at offsets: [34, 50, 75 = value, param, hq](https://github.com/viion/XIV-Datamining/blob/master/offsets/Items/items_csv_xivdb_unverified.txt#L15-L17)

+# Overall Item Level
+
+This one is really for gearset applications. 
+
+Item level is `*2` when involving two handed weapons, this is to compensate for off hand. You can test this by equipping only a Sword in game, then equip your Shield of the same item level and record the two values. Then equip a two handed weapon, your character will be the same overal item level as a Sword+Shield.
