I guess it is aggregation of both powerup and powerdown since I can see few negative numbers which I guess powerdown overflowed powerup.

By accounts would be great.
The bottom line is to figure out the trend: total LEO production (which I guess around 4800 or less) + powerdown - burned LEO - powerup :)
