2 drops for low resolution as noted in the instructions. If using low resolution x2 your result.

yeah the new batch says 4 drops for high resolution, 2 for low. Before it used to be 2 for high, 1 for low, but they've changed it for more accurate results. I like it, the new bottle is way better and there are no accidental drops like in the old one.
