This has always sounded like conflicting information.

With that said, if you want to increase the Treasure Hunter value, it is best to utilize equipment that has the Treasure Hunter+ effect. By unequipping Treasure Hunter+ gear, you are essentially creating a gap between the value placed on the monster and your character, which results in an inefficient means for increasing the TH value.
Adding TH+ does not increase the rate, but removing TH+ decreases the rate?
