As the Noobs FAQ points out, there are simple formulas to calculate the effect of the various input values on unemployment, transportation, and criminality.
However, the calculation of pollution is much more complex because there are interactions.
ind and env are the only individual contributors (increase in percentage pollution of ind * 5 / pop, and decrease in percentage pollution of about env * 7.25 / pop).
However, pop, tra, and com also have an effect, but it is in combination by multiplying it by other factors. The table below is an estimate that I hope to refine:
pop*com
 0.0032  pop*env  0.00275  pop*tra  0.0020  com*tra  0.0160  env*ind  0.0035  env*tra  0.0106  ind*tra  0.0080 
The interesting thing to do once these coefficients are nailed down is to use them to come up with an ideal strategy for using com. I'll post updates on this thread as I make progress.

Is it possible to hit cities with industry ??? So they cause cities to go down on ranking,
or do you think (like me), that it has little effect as long as positive clicks keep on coming.

As long as positive clicks keep coming, it's impossible to damage a city.
One thing you CAN do if you're trying to damage a city is to use the CMC Booster (on an undesirable stat) right after the daily reset, and use up as many known proxies as you can. This will prevent the target from being able to use those same proxies to recover.
I'm still working on a complete model for pollution so I can determine whether to waste any clicks on com.

great, keep the info coming.
It also seems Goon town has targeted BeatBox.Be Town. It's hard to find proxies that they haven't used allready.

The daily reset happens at 23.00 GMT (which i think is midnight in France). You should time your CMC proxy run to be happening right at that turnover, then you will get the first chance at the proxies.
I don't know if that time will change when they switch to summer time, but we have a few months before that happens.
Regarding my earlier comment, cities are damaged randomly when stats aren't perfect, but as long as you try to keep up with whatever they're doing against you, you can sometimes turn it to your benefit.

Hey, isn't France GMT? Or maybe I'm just a dumba*s

France is GMT+1 (winter hour) GMT+2 (summer hour) but we have some time before the summer hour

And back to the original topic.... I'm still working on reverse engineering the pollution calculation. I have done many experiments. This is what I know so far:
1. tra and sec have no effect on pollution
2. pop and com have a small effect on pollution, and the com effect is 2 x the effect of an added population
3. the effect due to env and ind varies... the bigger the difference (more ind than the env can handle) the smaller effect it has, so the first couple of ind cause much more population than those same ind added once there is already a lot of pollution. I think it might be an exponential increase. So the formula for population probably includes exponentiation.

I'm very surprised Motion Twin uses such rules, I was expecting linear rules only ... In this case, formulas will look like Ogame's one, not very simple to write a good model for this, and in this case it must be rather hard to collect significant datas... If we can help you, just ask other members on this topic...

I'm sure it's nonlinear if you are comparing to percentage of population.
But I was realizing, maybe the percentage is based on industry, not population. So I will play around with it some more. That would explain my data.

Hum no, we know that population have an significant influence on pollution, there no doubt on this

 Yes, I know this. I mean that instead of dividing by population to get percentage (like the other three stats) in case of pollution you divide by industry.
I have determined with certainty this is the case. I am refining the coefficients and I think I will have something to post in just a few minutes.

OK! I have determined the formula!
Pollution percentage = (0.1 * population + 0.3 * com  2 * env + ind  200) / ind
To calculate the integer pollution statistic, multiply percentage by 100 and round to nearest integer, but .5 rounds down.
Now, on to part 2, which is to determine based on this formula, whether it is useful to have com, or not.
