FWIW, I've observed that my potted JHAs use way less water than my potted LSU varieties. Maybe it reflects differences in the vigor of the root growth. But for now I'm assuming that the LSU varieties transpire water from the leaves faster. I know that the LSU figs were bred to tolerate wet conditions. Maybe JHA is better adapted to dry conditions. I guessing that, given excess water, it doesn't lose it so readily from the leaves, so the water goes to the fruit.
