Pop Reproduction rate mod possible?

[AMF]

Howdy,

Love the game. But, I do feel that the reproduction rates (population growth) that I am getting are rather unrealistic. Sometimes as high as 16-18%. I do understand that this is per year, not per turn, but wow! My people (and presumably others) must be rabbits.

I've mod'ed the settings.txt file a bit, and my average seems to hover around 8% now. I set "starting empire repro rate" to 1, and reduced uhh...another setting (I'm at work now, w/o access to the file to see exactly which one). I have, basically, lowered all relevant Ratings to 1.

HOWEVER, I haven't messed with the race stats Ratings. In there, there is a "threshold" rating which, for population reproduction is set at 10. What function does this threshold rating serve?

And what is the actual reproduction rate formula? Anyone know?

Ideally, I would like to get it down to a base rate of 1%-3% or so per year, with only moderate adjustments for happiness levels. Again, right now, even my "Angry" populations reproduce at around 6-8%.

Anybody got any suggesstions?

Thanks,

Alarik
