Where is my sanity?
Here's v3, which is exactly as fast as v2, but does random stuff on a different screen. I'm sure the population don't mind me playing around with the taxes. After all, there's no military unrest, or something.
I don't know how I filled up the long delay waiting for the attack ship to arrive, but I found a way. This might be mildly entertaining. Maybe. At least 10 times that of v2, anyway. Keep in mind that I probably moved the exponent from -4 to -3.
If I make a v4, perhaps I should question my submitting without first consulting the forums.
