sorry, i made a mistake, and corrected itNot bad, pretty close again
now it's a bit less good. Still reasonable but not excellent IMHO (4.5% error isn't bad, but it feels like an error)
for the sake of it, I calculated the SS0 from iteration 1 model : 975. So the new model is a LOT better!
edit 2 : my guess is the -22 represents something variable instead of fixed. Don't ask me what, though lol.
Maybe you get a discount for each star missing on your troops?
