^ ^a ^b Daniel Snider, ArenaNet API gitter - "Effectively, each item has a single generated number based on level/item type/handedness, etc. That number is then multiplied across those "multiplier" values you see in the response. The "value" is added on top of that, so the formula to compute a stat for an item is attribute_adjustment * multiplier + value where multiplier and value are from the itemstat response."

"Bonetti's Rapier has an attribute_adjustment value of 341.44 It's infix upgrade is https://api.guildwars2.com/v2/itemstats/161 so Precision will be round(341.44 * 0.25 + 0) == 85"
