I have a ship that is arround 4500 mass and has over 1 million e/sec. When on my own I can cloak this ship for a second or two but when connected to a station that has much less e/sec than my ship and about 900k total energy storage, my ship will stay cloaked and the power that is shared between the station and my ship will fluctuate wildly between 1k and 8/9k. The added power charge and power stoarge of the station are not numbers wise what is allowing my ship to be cloaked. I've tried this same thing at different levels of my own power production/storage and it was always the same, unable to cloak on my own, constantly cloaked but almost no power when docked to the station.
