It's probably mere coincidence but the problem is there are countless factors that could or could not affect or have any sort of gravity on Treasure Hunter's effects. The only things we can confirm to improve it is AF2 gloves and Thief's Knife, but even then it can be difficult to eyeball results from those given items, let alone to go by moonphase, direction, last hit kill and every other condition under the sun.
However, hopefully this will give more incentive to go level your NPCs! They're fun to mess around with for farming/item pop farming, etc. and can come quite in handy, especially for when that 6th member d/cs and doesn't come back for awhile.
