Downvote gallery block score

About text to image plugin, Anyone happen to know:

hideIfScoreIsBelow = -1.5 ...or -2.0...etc

The value is a ratio or count? For example how do I make it blocked when upvote < downvote, Or downvotes > 5?

Someone told me it's net downvote counts? However in some case it took many downvotes to take down a score of -1.5 or -2.0. is it because of delay?
