I thought it worked out as follows:
2 max lvl DE drills produce 200 DE an hour (100 DE per drill per hour)
The boost makes you produce 4 times as much DE.
So 200 x 4 = 800 DE per hour
800 x 24 = 19, 200 DE per day
My boost is almost up, and I have not earned nowhere near this amount of DE from the drills. I am under a shield and haven't trained up anything to use DE. Have I calculated this wrong?
