I did so looking in to this a long time ago i think it may still hold true; if the gear you're equipping favors you class but you are not of optimal rank the maximum you get off of it is 80% (at one rank below [did the check with a dodoskin harness and a leather jacket at rank 24 PUG]) and if are of optimal rank but it does not favor you class you get (IIRC)~66% (fingerless sheepskin gloves as a > rank 8 WVR).
