First of all: answer me this.
How could we be using nearly all of the planets power if we're not converting it directly into energy?
How do we figure we're .7? I see that it says that on the wiki, but it makes no sense.
In order for the Shivans to be II on the scale, they'd need to be using ALL of the power available from a sun. That's a ridiculous amount of energy, capable of vaporizing everything else in a given solar system. A fraction of that power would be necessary to create the entire Shivan fleet (as seen in game) over the course, of say, a year. How do YOU figure they're II?
And for the love of God, these are not rhetorical questions.
Unless you can prove that they do indeed use ALL the power from a star, (for something other than a nova) yours is the ridiculous comment.
